"I'll do a test to see what the difference in speed is with AS2's SetVariable."
There's a huge difference. SetVariable is near instant where EI has to encode/decode the value you are passing into/from XML. >From a browser you don't see the XML, but that's what's going on. The container is responsible for handling the conversion. What would have been great is to have a way to bypass the XML encode/decode if you know you just want to pass a string. I understand the beauty of being able to pass simple datatypes, but really, SetVariable hasn't been replaced. I'm guessing it was assumed that most people wouldn't be transferring a lot of data at once. Some people have created a hack of chopping up the data and sending it in an interval. You can still use fscommand to send data out without any encoding going on. The bottle-neck, then, is getting data into Flash. If you do use fscommand you might want to check this out: FSCommand and getURL Bug in Flash Player 9 http://www.northcode.com/blog.php/2007/09/11/FSCommand-and-getURL-Bug-in-Flash-Player-9 On a sidenote: SetVariable does work but it only sends to AVM1. So if you have an AS3 project and load an AS1/AS2 SWF, AVM1 is used for that SWF and you can get data into that SWF using SetVariable. The problem, of course, is that there's only one way to get data from AVM1 to AVM2 (without using EI again) and that's LocalConnection <shudder />, which is slower than EI.
