Yes, I think the way we will have to go is to demonstrate success of the Linux
port to the Indy.  If Linux on the Indy is a success then future projects
will be alot easier.

The 4mb RAM or so that the N64 has are almost rediculous in context of a
real operating system ...

The sad thing is many people see NT as the solution of this problem ...

Indeed, you're right and the ambiguousity of the aim IRIX has to solve is
what makes the chance for Linux.

Actually aside of the Linux developers like me there are also SGI engineers
interested in Linux as well as some ties on this list, so posting here was
a right thing to do.

I can well imagine that way can be found under which an O2 port could become
reality.  It's probably most important that customers (== $$$) ask for Linux
for their boxes and that word has to spread upto the higher managment.

I suggest to work on the Indy.  There is Indy code that just needs a bit of
polishing and debugging, but essentially we're relativly close.  Working for
the O2 would mean that you'll aside of a bigger technical task you'll also
have to solve a political problem.
