Well, that idea was brought in by someone else - I can imagine running
a distributed host on a cluster for rendering purposes, so its not
completely impossible someone wants to do this.

Also I thought of something like http as a protocol for
changing/advertising the parameters, not for constructing the actual
GUI (altough this would be possible and ease early testing of the
mechanism). And a java GUI communicating with a LADSPA plugin through
some standard protocol isnt the worst thing I can think of - at least
it'd be cross platform. I dont know java very well, but I can imagine
java having support for the http protocol builtin.
