I agree, its important to have both.

How so?

 My friend tried it out, and said it works quite well... But I sure as hell wouldn't
wanna try running Quake or anything like that under it :)

Wow strong feelings :)  I believe we stated it just for the sake of stating it :)
It would not have been forgotten.

And everyone will benefit... I know some don't agree... but I know everyone can
benefit from it.

That's kinda what I figured, but with our model it might be a little easier to
make.  We could have the primary machine make memory images of itself and transfer
them to the backup, and when the primary goes down (stops sending, or is observed to
be in lock-up), the secondary can jump into action at the same point the other left
off...

Only one problem I see here, and that is having a GIG of working system in memory,
and getting that to another machine... FDDI or ATM I think would have to do it...
