What I would really like to do is convince Intel, SGI, or some other MOB maker
to pay me to
write a filesystem and some other OS customizations designed for a MOB with
battery backed main memory.
You can probably all imagine a whole host of things you could do if main memory
was still there
after a reboot.

If any of you have any ins at a company that might find such a thing
interesting, please consider bringing
the idea to their attention.

Get Linux (http://www.kernel.org) plus ReiserFS
 (http://devlinux.org/namesys).  If you sell an OS or
internet appliance, buy a port of ReiserFS!  If you
need customizations and industrial grade support, we sell them.
