What does their existence cost you? Are you going to use the sunaudio module from the standard library? If not, is this an argument in favor of using C++ instead of Python? As for documentation, many people say it is lacking, but perhaps one person in a thousand points out _how_ or _where_ it is lacking. Unfortunately it is difficult to improve things (or even determine if they really are lacking) with this level of feedback. Keep in mind that in addition to the online documentation, there is a Twisted book, an extremely helpful twisted mailing list (with years of archives online), and an IRC channel populated at nearly all hours of the day with people who can answer Twisted questions. > >I guess I am wondering if given the fact I need a custom protocol, and need >to >talk TCP/IP should I stick with twisted or just use plain old sockets and >build it myself? Talking to the TCP/IP stack is surprisingly difficult to get right. Since it is extremely unlikely that you actually _care_ about all of the random, stupid differences between different TCP implementations, you should use Twisted, since it does its best to hide these differences and instead present a uniform API. If you use bare sockets, you will need to learn many of these quirks yourself, frequently through a bug report from a user, since many of them are undocumented. >Is there a third option I should consider?
