Do you currently use this? If so, how stable / usable is it?
My draconian work firewall is only letting me learn from Wikipedia: (http://en.wikipedia.org/wiki/Gallium3D)
Only know what I read about Gallium3D on forums & wikipedia, etc.
Regarding your work firewall, if you can access anonymouse.org or similar, you can access most sites - pm me if you need more info
