Have you seen this:
http://gsd.ime.usp.br/~lago/masters/
It is a networked LADSPA plugin. Maybe it could be made into a jack system.
What would be nice is to have something like your net client on one computer,
and a network jackdriver running the jackgraph on a different computer.
You do get one period extra latency between the two graphs.
