I must admit that I'm a long time Mac user, so on this front, my 
experience is much more limited than yours.

How does self handle text?  I didn't see any glue code that dealt with 
text, and so I'd hoped that self was doing the text rendering.  If 
that's the case, then GL's text support shouldn't be a problem.  I'm 
not sure what kind of 2D texture support you need....

You're also correct that GL doesn't scale down to low end machines very 
well, but it should be usable on 90%+ of the desk/laptop machines out 
there, which would be a good start.

Thanks, this looks to be an interesting read.
