I neglected to mention it here, but I released
some quick code to allow me to write text in OpenGL and C#. It's called FTGL#

The wiki page
has svn info
Disclaimer: I posted this in the mono category, but haven't actually tested it on mono yet.
Update: I have finally gotten around to actually running this on Mono (version 188.8.131.52) on Windows.
