- I think you are being more than unfair. How do you propose that SGI make
- your X terminal understand GL. GL doesn't use X to display on SGI machines.
- X is just a window manager for GL. They would have to write drivers which
- convert every thing they draw into the equivalent x thing and then pump it
- over the network. It would be so slow as to be useless for any application
- worth using.
-
- Granted SGI should have probably opened up the dgl protocol before now. Even
- IBM doesn't have dgl yet, even though they have gl. I think many companies
- will implement dgl and gl now that they have a chance, and then the X
- consortium will be compelled to follow.

- You could just get a the new X server from MIT and you would be on your way.

- Exactly. X is too slow to do anything much less GL.
