回答1:
It's not a question about the comet community, it's just that this is only half of the problem. You eventually need a comet client (such as jquery, dojo, or custom clients according to the server), but first you need a comet server to connect to (such as Jetty, WebSync, etc). Once you pick the server, you can then pick the client. If it's a Beayux client (such as the two servers mentioned) which is an open spec, then you can just plug in any client that supports that standard.
