Hi Ian and Brian,

thank you very much for your comments.

I am very curious on how the schedule you are planning will look like.
My plan is that I'll try to get familiar with Mesa/OpenGL in the next
months and then start full-time work on it in October (with the support
from some guys from our Cell team). It would be really great if our
plans would fit together and if we could collaborate on this.

Kind regards,
Alexander Schmidt
