These days it is very easy to make a very responsive web gui.
"Responsiveness" (the program reacts to user input) is not the problem I meant to describe but the ability of the program to issue "state" messages spontaneously.

This is hampered by the missing symmetry of the http protocol: The client needs to poll for such "reverse" messages.

This can partly be improved by techniques like "comet" that leave a http protocol open in a somewhat "non-standard" way. But AFAIK, this does result in certain problems.

Could You mention this problems?
