We should study what heavy ajax RC> apps like twitter, facebook and gmail do. Not sure this was already checked, but I looked at Facebook. At least on Chromium they seem to use long-polling for the first 7 tabs, using different sub-domains for each connection (apparently predictable, like 0-50.channel.facebook.com for the first tab, 1-50 for the second etc.). On the 8th tab they fall back to plain polling (still using different sub-domains, with the same naming pattern). I didn't investigate whether they also set different poll intervals for the >7 tabs (e.g. the 8th tab polls every minute, the 9th tab every 2 minutes, the 10th every 4 etc) , but they are noticeably slower to update than the first 7 tabs.
