answers, I  would be able to come with code]

The current httpdSecurityManager is broken, it is a remainder of some
old version of Jigsaw which did support PUT'able agents (you would PUT
a Agent, which would be executed server side). This first thing
(Agent) seems appealing although not as interesting (at this point) as
what follows...

Pretty near: one of the goals in designing Resources was to be able to
replicate them around the world, so that you would be able to
replicate the thing that *compute* content, rather then the content
In brief, pickle() a resource to a socket, you'll get an
agent. Implement a small inter-server protocol to replicate resources,
you'll get a really powerfull system.

Come with suggestion, I'll be glad to dicuss them.

Yes, this is the purpose of this mailing list

BTW, you should also check IBM's Aglet stuff (I didn't have time to do
it myself yet).
