Private push to talk server

SIP is getting popular in cellphones these days, but... push to talk
is there on 90% of new cellphones, already. I guess I'm not the first
one that would like to use that functionality for very simple VoIP, or
maybe for some interesting hacks. (Actually, skype is publishing
skype-lite, aimed at j2me cellphones... but it can't do voice).

Now, is someone doing that? Protocol seems to be documented, and patch
for asterisk (or something) does not look that hard...
