GWT support Comet/Server-side-push ?

[Zhong-zheng Xiao]

I want to use GWT to build a rich web apps, including subscribe-push model.

There are quite some libraries out there that provide push support for GWT including web sockets, server sent events, long polling/comet.

The two that I am aware of are Atmosphere https://github.com/Atmosphere/atmosphere and CometD both high quality libraries with somewhat differing feature sets, I think one downside to CometD is there is no provided GWT client whereas Atmosphere does have a GWT client.
