This is a great idea, in my opinion. In fact, would it be terrible to start porting in some of Aros' improvements? It's all open source reimplimentations of Amiga OS3.1, right?
I wish I could program worth a damn, 'cause I'd certainly like to help with things like this. Hell, if I had the knowhow, I'd write a warp3d driver for my Radeon card

People charge too much for the Voodoo cards (not to mention it'd break my nice flow of DVI to radeon and VGA to the indivision).
Does p96 or cgx have any hardware accelerated API within them? Or is that all in the warp3d and/or mesa stack?
