On the one hand, these apps are getting ever more popular (with new HTML5 protocols like Server Sent Events and Websockets) and it would be nice to support them; on the other, sending multiple, short messages over the same connection (HTTP streaming) raises some questions in relation to filters, MBR/MBW and the JAX-RS pipeline.

Just to clear, we could also support a broadcast operation without supporting comet-style messages. Essentially, by resuming the connection after the first message is sent. This would give us support for collaboration without all the other issues. JAX-RS implementations could support the non-resuming case as an extension.
