From your description that does sound a bit unwieldy for conventional RSS usage. Generally you'd have one feed/file and simply be updating that multiple times. However, a standard feed aggregator wouldn't be able to keep up in a usable manner. You might be able to get something working on your local site though with a high data refresh rate.
