i think is a good idea this, what is your opinion(s)?

I think mediator the first step is support for cybergraphics (in the past elbox work con cgx3 with virge drivers) but now not!
The 8mb memory window can be resolved using expansion.library (i think) and the env:mediator/emulation to YES.

Give them some time. I think if they are really interessing in they will find a solution.
