X11 has a swallow ability, too. I don't think running N toolkits in one
process is really what you want. I also don't think that LADSPA should
standarize how GUIs should look (e.g. using XML) or be built. Things like
aRts will definitely have sophisticated solutions for solving this, and
if LADSPA makes more assumptions than absolutely necessary about GUIs, it
will be difficult to get things working together.
Cu... Stefan
