So if we want to write our own client-side library. first we have to duplicate Dojo cometd code( http://archive.dojotoolkit.org/nightly/src/io/cometd.js ) which can be done with some difficulties because it depends on a lot of other dojo libs. But the worst problem comes form the protocol. It is a dojo fundation subproject so if protocol change we need to maintain our cometd client-side implementation. It seems to be an heavy work to do!
On the other hand I well understand you prefer keeping control of code you integrate in Wicket (and pushing is an interresting stuff for wicket). So maybe we need to thinking more about that and on impact on the future.
