I used to have an initrd that used two kernel monte to boot a second kernel (Allowed easy kernel 
updates over the network), A full busybox, Acme labs mini_httpd, Xfree, Wine and my win32 
application all in less than 15MB compressed. It used to expand to a ram disk and run completely 
from ram. Boot time off CF card was 45 seconds to a complete running system. It sat on a VIA 
mini-ITX board behind a microtouch or elotouch LCD touch screen.

I miss doing that kind of work :p(
