I'm a pretty intermediate c programmer, i have been programming in C constantly since more than year. When I say constantly, I mean nonstop. I've been looking to get into some open source development, but I really can't find any projects that I think I can understand. Most of the time, they're too low level (as in too close to hardware) or they are old enough that the lead developers have all left it. I am mostly interested in networks but anything interesting will do. For example, twisted (the python library), was a perfect match, but I'm looking for something that uses C.
