Great. Now a very important question: can the daemon be started from
Python without an os.system apparent for the user? I want to be able to
log in a box, and run a pPthon script that does parallel computing with
only a few lines of Python code.

Hum. Currently I am physicaly killing myself doing way to many things.
No, seriously, its worst than it has ever been, and I have a dangerously
off balance sleep pattern. Maybe I'll get better next year when I start
my new job. Maybe I'll even use ipython1 as a full part of my day work.

That's really nice. Now a big question is, does that remove the need for
all the objects in the parallel code to be picklable. Because that is
what was limiting me here.
