Good point, I'd forgotten atheos was using it also. OK, you seem to know
more about this than me, i'll take your word for it :)

I know the wineserver supports IPC between wine applications. Perhaps if
it doesn't already support it, Wine could be extended to allow a DC to
be drawn to by another process that's connected to wineserver. Not sure
really. Although I don't think X11 gives an easy way to draw to another
window, you can embed one window seamlessly inside another using
reparenting. One solution might be for the WebControl to be a simple
"socket", that allows other things to be plugged into it. The browser
server then creates a window containing a KHTML control and reparents
it. That way you'd avoid having to rewrite KHTML to use GDI, instead it
can just use X11 directly. Or would that cause issues with Wine?

Yeah, also the KHTML code is far easier to read and understand than
Gecko from what i've seen. Does the licensing thing mean that if you
write a KDE app it must be GPLd?
