Okay, so reword my previous comments to something along the
lines of "this assumes that they require the same protiens,
etc. as we do to function"... granted, there's a much
greater chance of this than us being infected by an alien
virus, but I assume it is still possible that their
chemistry/biology can be sufficiently different to make
infection harmless.

It's not my strong point, but didn't I read somewhere
once that while a lot of the proteins, etc. we live on,
while they can be either L- or R- versions (left handed
or right handed), are all mainly L-?  I think I read a
short story where someone went through a strange experiment
and came out with an R- based system, and no one knew it.
He was slowly starving to death because his system couldn't
use anything he ate.  Or am I barking up the wrong tree
