well, i followed the previous thread and it's my first mail this morning.
* jabber.helixcommunity.org merges helix and jabber
* question of belief whether p2p or server
* server allows more control, i.e. to ban kiddiepornsters on public servers
* good NAT traversal in a few years won't solve anything now
* TCP is more than sufficient for speex data transmission
* speex crunches 1600 bytes of PCM into 21 bytes of speex (YES!)
* political question whether we should agree to ONE codec or design a codec independent protocol
* Skype constantly (about every minute) causes communication disrupts
* judge yourself is this is good or not
* 1-to-1 chat and MUC cover all use cases for voice/video as well
* consensus in this unified multi media messaging protocol needs to be found

I didn't really follow the previous thread (sorry), but here is my take:
We really need to define a standard for this ASAP. Even if half the client authors never intend to implement voice (and video) we still need a standard for those that do, otherwise we will be stuck with a bunch of clients that can't talk to each other - and then we are really no better than the MSN's and Yahoo Messengers of the world.
I say we go P2P. If anyone has doubts, they should download Skype and have a play with it. I think we need to look seriously at STUN as a NAT traversal standard - I believe this is what Skype uses and it seems to work very well.
Speex looks cool for an open codec (not that I have looked at it in detail)
I think this "Upgrading" from IM to voice is really going to take off in the next few years. I do it a bit already at work with the phone, and it's "Umm...what's your number...ok... *dial*...*ring*...Hello?" It's going to be so much more convenient when you can just click a button in your chat session and start talking to your computer.
Voice conferencing would be very nice to have (again Skype just added it) but user-to-user should be the first goal. I suspect something like 90% of telephone calls are between two users.
Video (webcams) have a big "wow" factor that currently is only limited by bad NAT traversal. Expect this to take off in the next few years also.
