I like this thing. I had changed the purpose of my robot firstname.lastname@example.org. Now, when added to a wave as a participant, it will post all blips on http://maison.appspot.com ;-) So blips are now really public ... and can be seen by the rest of the world ;-).
Perhaps you will fall in love on what's happening in GoogleWave. A lot of interesting discussions ;-).
It's just a kind of concept, for fun purpose only !
Amazing ... Today I had received my google wave account, and started to play with wavelets, blips and all these newer things ;-). Really amazing. I really think that it could be the next big thing in the social/communication side of the web.
It takes me one hour to developp a robot (email@example.com) which replace the word 'fuck' by 'f**k' in all the blips of a wave ... amazing. (Edit : my robot has generated a lot of blips in a wave (wavesandbox.com!w+UyA_PnlT%A) yesterday night ... really funny)
Now, I can't really think all things that could be available in a such system. But as always: APIs from google are just perfects ... they fit my brain. Every thing can be done using python and GAE : just perfect.
EDIT : A really good introduction to present what google wave is (in french)
