Wu,

Thanks very much for making this announcement.  I'm very excited
about this work.

I had a chance this week to meet with some of my colleagues inside
Sony, who are working on projects with Linux that have a RAM budget
of 3 meg. This and related size work is really important for us.

P.S. For those wondering, while our RAM budget is only 3M, we
have 8M of NOR flash, and we are using both kernel and application
XIP.  The system has a full network and bluetooth stack, sensor
monitoring software, and a web browser.
