Exactly.

Well... If the "net wrapper" plugin has a GUI part, just make it a
net view window, where you can manage public connections of the net,
and pop up the GUIs of the plugins. (Or show default GUIs for plugins
w/o custom GUIs.)
Theoretically, hosts won't have to be aware of this at all, but there
may be things that can be optimized a bit if they do - not sure we're
talking *speed* optimizations here, though. (Publishing a port of an
encapsulated plugin should only be a matter of forwarding connections
to the encapsulated plugin, as connecting is actually just telling a
plugin where the buffer is...)
