Outside of encrypting in SSL, how can variables being posted from the browser 
back to
the server be protected from prying eyes?

encrypt it yourself? but you'll also need to provide a decryption tool for the client side. this can be javascript (google for javascrypt from fourmilab), but really, why not use ssl?


During previous pentests, I've seen variables being posted to a webserver 
(IIS6.0 is  one I
remember this with) all hashed together. I don't think that any special 
client-side software
was used, it was a function of the site....

well hashing it won't help at all. you can't reverse a hash.
