also in the Rex prototyping I mentioned earlier (helped with it a bit in
December and November) we used pjsip, using the python bindings for it -
eventually the 'simplesip' project which is a Pyrex written lib with
msrp support on top of pjsip.

we also ran against Freeswitch, both local and the friendly sip2sip
online service (to test msrp etc thru two clients behind NAT).

yep like i think i've rambled here earlier when XMPP was discussed, it
is interesting how there is overlap with OpenSim and the IM/presence/etc
techs, as they are largely about presense and communications (albeit
spatiality and 3d are the other strong aspect in VWs)

was good to hear you've done similar things and more too (we didn't
touch opensim in those experiments at all, just client side stuff).

let's keep in touch,
