+1.
Just use an XMLHttpRequest to regularly ping server, say every 30 seconds.
There are other related techniques: You may use an IFRAME and autorefresh
it, instead of refreshing the entire page and hence losing the viewstate.
...
On the java side, once upon a time there was something called pushlets.
Namely a servlet which does not close the stream and continously push some
data to client. I don't think there is something similar on the dot net
world. Besides the java pushlets had problems of their own.
