Hello Misters, As you are OpenGL experts, I am  asking your help.  I am attempting to build up a team.  I believe it's time for a full-fledge verified OS. The graphic part is essential nowadays. If somebody is interested in functional programming and in formal methods to help to implement a xserver with HOpenGL and XHSB, he is welcome :) XHSB ( X Haskell Bindings ) : http://lists.freedesktop.org/archives/xcb/2006-January/001278.html Here is an example of a protocol formalisation and a trusted GUI : network stack : http://www.cl.cam.ac.uk/~pes20/Netsem/ If you want to contact me, my mail is guillaume_dot_fortaine_at_wanadoo_dot_fr I will set up a mailing-list, a web server, a wiki and an IRC Best Regards,                           Guillaume FORTAINE
