GUI to control multiple remote hosts (using the same GUI for simulation and real hardware)

I've a GUI based on python and gtk, my program manages varios applications in the same machine using subprocesses, i.e a button launchs an emulated host, another button connects it to a switch ... now I want to but each component in a separated machine (so开发者_开发知识库me hosts will work as soft switches, others may work as routers...)

I may link GUI to machines by sockets, xml, spawning ssh subprocess or using telnet, I also find that fabric may be cleaner than handmade ssh sessions.

Q: What is the easiest, most robust technology to use? I don't mind installing any client on the controlled machines.

Answers based on similar experiance would be great, but also any suggestion would be helpful. Thanks in advance.

Since you already have a mechanism that works to spawn the processes on the local machine, it sounds like the only thing you're lacking is a way to spawn the processes on the remote machines. I would go with simple ssh connections as it would require the fewest changes to both your infrastructure and your code.
