Sure. We already have TCP/IP plugins, they just don't do capsnego across
network yet. This should be easy to implement, though.

The things, which comes across in my mind is discovery of the various plugins in the network, Classifying them and finding out whether they are available or not at any particular instance. I am not sure, how difficult or easy this is.

Sure, but you're being very general. My guinea pig could make that
choice too, if you understand what I mean. What are you aiming at
exactly?

My point is on what basis are you going to make a decision to get the best quality of service... number of hops, efficieny of plugin ( how will you make a decision on efficieny ?) etc

Note that we don't actually do QoS yet, although it's planned to be
worked on some day. I've got some ideas on it, I just don't have time
right now. Or rather, QoS is not a priority for me right now.
