Most of us fall toward the lower end of "constant work" and "zero contribution", honestly, since the majority of us are doing it in spare time and not getting paid for it.  What is needed is a long-term commitment to fix bugs if they show up when new changes are made to CPython.  Which is where a buildbot is fairly critical...and I have no idea how complicated it will be to set up a buildbot for your environment.  I think it should be possible, though, since buildbot and twisted are written in python.
