It would work, XUL + ECMAScript is quite a powerful environment (I've built
some significant apps in it), but it only really makes text based widgets
easy to manipulate, and its sloooow.

Agreed. I'm half ported meterbridge to OpenGL and the code is actually
simpler (and /much/ faster, even on my ageing laptop) than the native SDL
I wouldnt want to use OpenGL if you had a lot of things like scrolling
text panes, but plugin UIs are mostly sliders, meters and graph displays
which are all easy to do in OpenGL + pixmaps.
