actually the more I think about it, orbit doesnt really worry me that
much since it's in a different process space.

This interests me, but unforunately I was only musing about the
difficulty of using gtk and orbit.

For now I just need to use python-orbit and threads.  gtk is the next
step, so you can bet I'm going to be back... 8)

Now here is where my naivete comes in about extending the python
interpreter.  Is it possible to have pyorbit release the lock right
before it blocks and then after it unblocks, re-aquire the lock?  It
just cant be that simple I'm sure.

I'd be willing to help out with this, but I'm going to probably need
some help figuring out some of the internals that I dont know already.

if all goes well i'd help out there too.
