I have tried to find out before, but is it possible to get RefTagger working in Google Wave?
all about Christ,

David:
I looked into this a couple of months ago, but couldn't figure out an easy way. You can't directly modify the Wave "template" in the way you would a WordPress template. I think my conclusion was that it would involve coding a Wave Robot that runs over the wave and modifies its contents. For Python, that in turn requires getting set up with Google App Engine, which is about where i ran out of attention span. The Embeddy robot is supposed to provide an example for interacting with wave content.
