Have you considered using pyro? http://pyro.sourceforge.net/ > This is a *really* bad idea. How do you know for sure? Maybe the OP wants to use this thing with 3 known researchers working on a cluster that is not even visible to the outside world. In such a setup the model the OP suggested is a perfectly reasonable one. I say this because I often work in such an environment and security is never an issue for us. And I find it always amusing that whenever I outline our code to a non-scientist programmer they always run away in shock and never talk to us again :) Nevertheless our code works perfectly for our purposes. > Because there is no real way to restrict > execution in python, and thus you allow clients to inject arbitrary code > into your server.
