That would have been a project I would have loved to do (I loved working
on mips). But now I'm just too busy and don't have anymore mips boards
around.

I can't think of any gotcha's off the top of my head. It's been several
years since I've worked with MIPS.  There may be some funniness with the
way MIPS addresses memory. But I'm not sure. I'll have to think about it.
