Contributions are always welcome. ;) If you or somebody else will do the migration please open an issue in https://issues.apache.org/jira/browse/COCOON3 and attach the diff.

Actually I am still thinking on implementing comet http://en.wikipedia.org/wiki/Comet_(programming) Actually long polling should not to be too complicate to be implemented with our REST framework (hopefully I will find some play time for implementing that). ;) However html5 will open some new approaches to the comet technique where Server-sent events and websockets come into play, but I think there we need to make some changes to our controller.
