For what you're doing and the limitations you have mentioned, I would
go with OpenID, that way you rely on third parties to do the
authentication, and I think in most cases it will use https.  I have
used Spring Security to quickly setup openID as an authentication
method (although I have never run within appspot, so can't help with
specifics for your case).
