Ok, good to know. As far as I can see, an off-the-shelf pub-sub system is propably enough for this purpose, and I'm not really planning on studying the pub-sub itself, but rather how to utilize it. 
I'd very much like to choose a system that is robust and can scale up, eventhough at this phase and in my hands, a p-o-c is the level that I'm targetting.

I'll look into those, thanks!

I'm hoping to have the environment ready to use for a basic user, and familiar for a developer as if dealing with any software objects. I have a clear picture in my mind...

Sounds very good! So far, I try to restrain myself from moving to even more foreign terrain until I get the architecture easy enough for me and others to use.
