No, python provides no such mechanism. However,
I would highly recommend you take a look at circuits (1)
for this task - as it's been especially developed for
distributed processing in the manner you describe above.

In order for your program to propagate itself, you would
have to rely on ssh (recommended). There are several
good ssh libraries/clients for python, and pexpect might
come in handy as well.
