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

please don't suspect - give a source for your number. i don't believe 
your 90%.
