How about a special system of notification through Google Gadgets for Gmail? A setting in Google Labs allows users to add a gadget by URL. If we could have a Buzzword gadget, it could give us popup reminders when we have updates to our documents.

This approach would prevent a barrage of emails when multiple changes are done to multiple documents.
