Yea, I work quite a bit with government contracts, and to be honest it's a lot of fun and it offers some very interesting projects and R&D opportunities. But I work for mid sized consulting group that has at least two layers of insulation between me and the customer. My boss is an absolute hero for dealing with the stuff he deals with to make sure I just get to code. There is no way in hell I'd try to get involved in that world if I had to deal directly with the whole procurement process myself.

Also I try to only take smaller projects (up to $100000 or so) since they tend to be handled by much more sane people all around.
