Lithunwrap is holy! Holy I tell you!
I use that program too to unwrap models I imported into Max 7.
But Lithunwrap does havs it's limitations, it can't handle the complex models I make for my job. So I use another program, but that's an other story.

I heard many good things about Wings3D. I suggst everyone takes a look at that and try to make something out of it.
I think someone here (maybe David) posted a link to another open sourced 3D program. I think it was French, but there was an English translation Dl'able.
