Is there anything for Python that has concurrency like Erlang does, particulary transparent actors over networks? I've looked at things like greenlet and stackless, but they don't seem to have network transparency for actors.
I still can't quite jump the hurdle of Erlang/OTP so I'm interested if there's something closer to home.
Not really. Erlang was designed from the ground up to support actors, Python wasn't. The closest I can think of that fits the bill is the Candygram library, but even that's not quite right.
