Dear John and Cristian,

I forwarded your last message on this thread to Apple's director of the
Science/Technology market. She has been quite responsive to requests in
the past. I'm sure that it would also help if others did make their
interests known through their own academic, government, or corporate
channels.

Thanks,

Jim Nettles
