I prefer to think of a GUI toolkit as something you use to construct=20
and run a GUI, period.

The other stuff is done using some other lib, such as a GMPI API lib=20
that lets you connect to plugins running in other applications. (Or=20
perhaps, lets you run as an out-of-process plugin that the host or=20
user can connect as desired. I prefer it that way.)

I wouldn't. A GUI toolkit that works for more than some 80% of plugin=20
GUIs (at best) is basically the Holy Grail of GUI programming, and I=20
don't expect to see a useful implementation any time soon.

Maybe we're not *only* audio hackers around here (any people with=20
experience in designing serious GUI toolkits?), but a GUI toolkit is=20
*really* beyond the scope of GMPI, I think.
