pygowave-server
Implementation of the google wave server written in python before google even released the reference implementation. Very impressive.
Allows for multiple users in a single wave, has the fancy real-time typing, and allows for upload of custom gadgets which everyone can use. Only allows one gadget to be used at a time and has no “default” functionality, purely the server being used through gadgets.
Still, some of the gadgets are very impressive all by themselves, and show how useful Wave could be once you’re able to use multiple gadgets at the same time. Mappy in particular is definitely worth a look, and then of course a chat client or two.
Anyway, have a look, it’s cool. Kudos to the developers.
