Yep, that's what OpenGL can handle exactly.
There's also the case of multiple screens surrounding a person with
different viewpoints or the CAD way of handling multiple simultaneous
displays....

I'm just remembering that GGI -> svgalib emu -> GGI isn't allowed...
but XGGI -> XGGI -> ... -> oh, fbdev
works.
Right, no prob.
Will start looking when done current projects (ecommerce server + a whole

G'day, eh? :)
