I have also been employed to work on open source software. I actually didn't really think of it until now but it is nice to still see stuff going on in the project. I am still on some mailing lists plus I get notifications of tickets I previously touched being modified, commented on, resolved. It is also still quite within my capabilities to jump on and fix the occasional bug if I so desire, or just provide some thoughts on issues others are working through. As you mention, the proprietary software companies I have worked for are very different. By close of business on your final day you are locked out of everything.
