Yes, I thought it was doable. I learned more about the target
application this morning. It sounds like it will be more like a
bootable CD situation with a read-only flash as the boot media.

The application can use a RAM drive for boot logs so digging into source
code will not be needed. It is so cool that it could be done all the
way down to the souce level, though. Free Software is great!

How did you know? ;^)

Thanks for the response.
