I've been thinking about joining OAA, we'll see. I hope the development goes on, an integrated message bus from front to back is the way to go. I was tinkering with such an architecture in 2000 when we founded a wiki/blog/ontology/tagging (knowledge management) company, but technology was not ready. Great to see it come to reality.

As your example shows, you can easily add it on top of what's there, but the speed of iteration and string manipulation on slow JS engines (IE 6 and 7 in particular) makes it relatively infeasible. Even implementing hierarchal dispatch in the OAA hub was somewhat controversial for similar performance reasons. Also, what happens when you call connect() a second time? For a script that will get passed around the net billions of times a day we decided to be somewhat hands-off about this (as I also had done in the even-simpler Dojo pub/sub system). There will be an update to the hub at some point and you can help us define what should be in it by joining OAA or the hub mailing lists.
