Exactly. Someone mentioned above the ability to create intelegent objects, imbued with a certian degree of independence, including the ablity to be places that you are not... that is, to fork. Agent Smith managed to do this to the point that he overwhelmed the resources available on the server. We need to guard against such an occourance, which could potentialy raise to the level that the machine would become unusable (though, I should hope, not to the point that The One would have to sacrifice himself in a christ-like manner to kill -9 the bastard...). Anyway, the idea is to give each user a cputime limit, and enforce it... though I'm not quite sure how to manage that.
As to colabarating, I'll try to make my code public as soon as it's minimialy usable... it's still very much larval.
Update: if it wasn't clear, my moo was just started last night, in response to the root node.
