It occurred to me that a profitable thing to do here would be to mention some things that would be nice to see in a new improved TeX... I believe bidirectional was mentioned already.
The other thing that is essential for folk like me is complete Unicode compatibility [Yes, I know. UTC has committed many sins :] BUT: just so it's clear to everyone that I'm not just trying to get goodies on the backs of other people's hard work--I'd be more than willing to help in due course. First I have to get a Plan9 installation, though, and I need to acknowledge that I'm relatively unfamiliar with the guts of TeX at the present. So one step at at time :) K
