Event listening across IS relations works, with simple example in examples/event/index.html. Now you can change one node and IS-related nodes will also change. Bidirectional, but endless looping is suppressed. TODO: currently listens for DOMNodeInserted.. needs to listen to some sort of ValueChanged event instead, but I'm on an airplane from Jakarta to Bali and can't look up the DOM API :)
Just finished renaming funcgtions from nodeinserted to valuechanged, since that is the eventual intention. landing in baligruntgrunt
