Seeing "immediately" what others are doing on the same page and viewpoints

[benel]

When Firefox parallel and asynchronous computing mechanisms are stable enough,
replace the polling system with a notification system.

Note: To reduce the opened connections on the server, it is is probably better to implement the "filters" (on opened item and viewpoints) client-side rather server-side.
Note on the note: Then the cache may be reset by the observer rather than by the RESTDatabase itself.

BTW, did you try with "longpoll" instead of "continuous"?
In the RESTClient, it works far better...

It will be easier if couched support eventSource (HTML5):

@chao It seems that CouchDB 1.3 brought eventSource:
