Alien Design Notes

So, a while ago_sps_ and I came up with some notes for
designing Aliens that didn't borrow heavily from convergent evolution
(no bird-men, fish-men, lizard-men, bumpyhead-men). The notes are
really just a first draft of a checklist but I'm thinking of turning
them into the outline for a book and perhaps trying to interest Hero
Games in publishing said book. It won't make me much money, but it
might be fun to do.

Anyway, I thought I would post the current notes here in case anyone
had any comments on them...
