You might also want to have a look at the Wave-API group (at http://groups.google.com/group/google-wave-api).
In the discussion "Google Wave Inbox Notification tool for the Windows Desktop" (post 15) pamela noted that reverse engineering parts of the service might not be permitted. I don't know if the same thing applies here. The protocol should be part of the open source specification. But i see similarities (since you wrote "Reverse engineering".)
