WebPagetest will always be free and there won't ever be subscription services. I like it that way as it's less complicated and simplifies building a collaborative community (also makes it easier to not have to support SLA's, etc). I am looking at various options along the lines of what you are talking about.

The code already supports running tests at different priority levels so the recurring testing would be given a lower priority than on-demand tests. Would just have to keep track of capacity to make sure the system didn't get over-provisioned.

As far as storage goes, even the hourly results are not a problem - where things get to be intensive are the storing of the screen shots, http headers and the transaction details needed to generate the waterfalls. For recurring testing it's likely that screen shots and http headers wouldn't be kept at all and the details for the individual requests would only be kept for X days.

It's all easy enough to do, it just takes time to implement :-)
