At work, we routinely forward OpenGL over ssh. It works as long as both |
| 9 |
machines have the capability of rendering. One just needs to make sure |
| 10 |
both of the following options are enabled: |
| 11 |
ForwardX11 yes |
| 12 |
ForwardX11Trusted yes |
| 13 |
|

As a test, I just logged into a machine at work from home and ran |
