Now that real SIP (not gizmo) support has come to the N800, only one thing remains for me to be head over heels happy with my N800: Encrypted VOIP.

Skype does not count, as they are using a closed, and rather suspect crypto scheme.

Phil Zimmermann, the creator of PGP, has a free software tool out called Zfone (http://zfoneproject.com/). It's super cool, and plays well with all the SIP clients out there. It's open source (in fact, he doesn't ship a linux binary, only compile your own source).. and it needs an N800 port.

I really don't know what I'm doing when it comes to porting apps.

So instead, I'll put my money where my mouth is, and offer $25 to the first person who gets zfone working on the N800. I know it's a small amount, but I'm a graduate student. Hopefully, others will chip in too.
