You are probably right, but an Apple-only solution won't cut it in the real world. I wish you were right about your claims of FaceTime being a completely open protocol. I am skeptical. According to this article, it appears that FaceTime is entirely dependent on Apple's proprietary push service (which appears to be a proprietary implementation of XMPP,) instead of the XMPP-JINGLE open standard, for invoking the SIP session. http://www.packetstan.com/2010/07/special-look-face-time-part-1.html Based on this analysis we can determine several critical pieces of how Facetime works: * Unknown TCP protocol starts the conversation, likely initiated following an event that starts on the GSM network; * Unknown UDP traffic between two hosts with similar IP addresses; * Certificate validation through an Akamai server, followed by an HTTPS request to an Apple server; * STUN traffic for NAT traversal; * SIP traffic for call setup and negotiation; * UDP stream data for video/audio. FaceTime may indeed be more open than Skype. But if it cannot exist without Apple, it is not actually open.

All I can tell you is that Apple has said that they are committed to making Facetime a true open standard. Whether or not they actually deliver on this promise is something that only time will tell. Certainly, what we know about Facetime so far is that it is largely built on existing open standards, and even if Apple didn't deliver on their promise, I would hope that it wouldn't be too hard to create a real open standard that delivers the same functionality. At that point, Apple would be forced to choose whether to continue with their proprietary implementation or support the open standard. Since part of the purpose of Facetime (and Apple's claim to be committed to turning it into a true open standard) is that it would give them a really strong weapon to use in their fight against the Microsoft/Google/Skype Hegemony, I think Apple's choice in this matter is pretty clear.

I can also text a dumb phone by supplying the fully qualified phone number and going through AOL. So, the question is really about choosing a means of interacting that is supported by a sufficient spectrum of clients. Or for an individual to choose a client that is sufficiently broad to connect with whatever means of interacting you settle on. So far, iChat has done everything I've wanted to do and then some. My daughter has had smores parties (heated over a candle on her desk) and pajama movie parties with a friend who lives 2000 miles away, connecting from iChat with an iSight to whatever the friend was using on her PC. They could giggle together and talk while watching the same movie.

Whereas I use Skype on a daily basis for text chat (including one-on-one and group multi-chat), and I've used it for both audio chat (group) and video chat (one-on-one). I've also used Skype on portable devices, like the iPhone. If I read this right, chances are that factime is just a very good client to standard protocols (and yes some libraries will do a better job at encoding/decoding H264), which would mean that: My experience with Skype for audio chat is that it's actually not that good -- lots of drop-outs, people getting dropped entirely from the chat, etc And everything depends completely on who initiates the chat -- you're probably okay if they're on a high-speed DSL or cablemodem line (10mbps down and 1mbps up), but you're screwed otherwise. And it seriously, seriously sucks for one-on-one video chat. I have found that iChat does much better video and audio quality, even when talking to an AIM client on the other end. In contrast, Facetime totally and completely blows away everything else I've ever seen in this space, at least with respect to the kinds of systems that individual people can afford. If you want to build a media cave with hundreds of thousands (or millions) of dollars worth of Cisco or Tandberg equipment, you can certainly do better than Facetime -- at least, with regards to the quality of the video and audio signals, etc But even the most expensive equipment you can buy cannot possibly hold a candle compared to Facetime with regards to how trivially easy it is to actually make that connection and start using the service. Now, instead of comparing Facetime on an iPhone to Skype on a desktop computer, let's compare them both to the same hardware platform. On any handheld device I've ever seen, Skype seriously, majorly sucks huge planetoid size boulders, just with trying to keep up with group text-mode chat. Any irc client from the past ten-plus years would do (and does) far, far better. The problem is that few people on desktop computers these days know anything about something like irc, or are able to install and configure the software so that it works for them.

Skype is proprietary and have innovated a lot, I believe nobody else pools bandwidth the way they do. Is this for a company? How big?

It does voice and video, but, I don't believe there are any physical dedicated devices for it, so it'd be pc to pc only. You mention openfire, I have been very impressed with openfire, but I have only used it in small setup so I don't know how it scales. You can also federate with other servers if that is a requirement, so you could do IM with people on gmail etc...
