I wasn't able to get ape-server working for the same reason: MooTools 1.3. The more I read on this topic the more I realize the trend is toward WebSockets anyway, which isn't all there but is a real solution. Comet is more of a workaround. Given our focus it probably makes more sense to build to WebSockets and only support a limited set of browsers.
In any case, it looks like socket.io is next on my list. Mike
