Assuming that the info will be made available in html format, the only thing you really need to do to achieve c) is to choose an appropriate value for the http-equiv="Expires" meta-tag when serving the info, and have a cron job at each ISP make a request for the info at some arbitrary time. This last step really isn't that useful unless there are points of congestion, or times when the servers are bogged down. The caches have to respect the Expires tag, though, and a broken clock can cause all sorts of fun on that end... -- Bob <melange@yip.org> | Please don't feed the sock puppet.
