You mean *easier* than adding/removing RAM. I still think it wise to turn
power off before I modify the physical RAM :), however, I'd like to add/remove
processing nodes w/o that bother. Also, I'd rather see a multi-p OS just built
around the F21 or other MISC. The idea of having special processing nodes to 
handle specific IO tasks for the OS (such as a hard-drive interface) reminds
me of the Transputer systems that even went so far as to have specific variants
of the node hardware built for these specific tasks. Do you want to go that
far?
