If you were to give me CVS access, I'd commit fixes for bugs that affect 
me (but those fixes might break non-Gentoo), and maybe documentation 
related stuff.

(in the list below, - and + are from Fluxus' point of view)

- I've never used cvs other than anon checkout
+ I do use svn for my projects, so I know roughly how versioning works
- I can only check things work on Gentoo (two machines to test on)
+ I can check ATI vs software rendering issues
- I try to avoid C++ wherever possible, too painful
- I've got into Haskell, which makes Scheme seem painful
- Haskell OpenGL bindings exist
- Haskell has a REPL interpreter
+ Haskell REPL is incompatible with Haskell OpenGL, because HOpenGL 
requires calling mainLoop which doesn't return
+ Haskell liblo bindings might not exist
+ Haskell libode bindings might not exist
- Haskell nD matrix/vector libraries exist [1]
+ I wrote the one I use
- I wrote it in Haskell

However, I would probably want to port Fluxus to use Haskell instead of 
Scheme, which would enrage everyone using Fluxus ;)

Unless... I did it in such a way that you could have both Scheme and 
Haskell scripts in the same running instance of Fluxus?

How language-agnostic is Fluxus' core?

In hsext [2] I call C functions from Haskell and call Haskell functions 
from C, both directions using the C ABI.  Haskell has a mechanism for 
wrapping a Haskell function into a C function pointer at runtime, if 
Scheme has something like this and Fluxus uses this to call Scheme code, 
it should be (relatively) easy to add Haskell support.
