GAE has limits on how long a request can take before it times out, so long running collection processes within a GAE request wouldn't work. Additionally, there is no scheduler service in GAE at this time, so there is no way to periodically go out and collect the data. You would have to do this externally. I did see an app in the Gallery that provides a scheduling service for GAE. You might be able to use that. I would create an external service that does the collection and posts the data to a GAE application API. You could then present the data in the typical way.
