I'm glad you've published a summary of your work in a public forum, so this 
effort becomes more widely known. What does this mean for a potential GSoC 
project. Do you think such a projet would "get in the way"? Or would you on 
the contrary see fruitful ways to collaborate and would you be willing to 
mentor the project? Either you or Aljen would be the ideal mentor. If 3D 
accelerated compositing in the app_server would come into play, I could 
imagine I would be an ideal backup mentor for when the project takes shape 
and the app_server changes are the next steps.

Best regards,
