Freemed and AAFP! Freemed has been making steps forward lately. The project is now being funded by a non-profit group created just for this purpose, Freemed Software Foundation
Note that I am hardly impartial.)
The Freemed Software Foundation is in the process of talking to AAFP about coordinating their open-source initiatives… according to this letter!
For those of you who dont know Freemed is an LGPL open source Practice Management application. Unlike other projects, freemed is focusing on solving practical problems for doctors in private practice. It is the only project that I know of that has a working billing system. It also has extensive support for different languages.
