Voice over GPRS?

With a point to point link what would be the minimal software stack
needed? There's only so much CPU, might it be more appropriate to use a
relatively lightweight process to rx/tx+encrypt/decrypt the data?
In any case, the idea of an open encryption standard for cell phone
communications is pretty appealing.

That's what www.cryptophone.de does to avoid latency issues. Some
block mobile to mobile data calls though.

It doesnt need to cost a bit. In fact, this is why I am on this list and
why I'll be getting a Neo phone. We presented at CCC:
The video is available at: http://chameleon.cypherpunks.ca/
In essence, a phone using Openswan, Xl2tpd, openvpn, pjsua, Jabberclient
talking to an
server running Openswan, Xl2tpd, openvpn, asterisk, jabber server.
We hope to have Neo firmware available before you can order the hardware
For more details, see our presentation.
