RPyC !
I personnaly used it (and its predecessor, pyinvoke) for:
* a testing system that controls several computers
* drawing graphs with matplotlib while avoiding its memory leaks
* distributed calculation
* controlling embedded python applications from my favorite python
shell (not the embedded one), also allowing me to control several
instances of the application.
it's so easy to use that there's was no effort require to do any of

it's pretty self-explanatory, so I'll only say this:
it's Transparent. you run remote code and access remote objects just as
you would locally. it's minimal, and complete.
I highly recommend it!
