There doesn't seem to be any way to verify the authenticity or integrity of
events or any piece of data stored in the wave.  The best workaround is to
store your state with your gadget (e.g. in an appengine data store), but you
still have the problem of being certain that the gadget you're interacting
with in the wave is *really* the gadget you expect to be there, and not some
evil/malicious gadget there to capture your credentials/data.

I have ideas for some gadgets that I've effectively shelved, because they'll
never work safely with the API as it stands today.  :(
