Hmm, if you want a "complete plugin <=> UI split", doesn't that mean
something like the lv2_external_ui extension, which puts the UI in
a separate process (perhaps even on a different computer), rather
than the libsuil approach that could easily lump the host, numerous
plugins, Qt, GTK+, and who knows what else (GL? SDL? segfaults?)
all into one process? Or am I not understanding what you mean by
"complete split"?
