The plan is sound, and the new beta service is getting better by the day but I'd advise against making filters a premium service. After all we're talking e-mails here, whereas these days it's insanely easy to employ user-end filtering within e-mail clients, desktop or www-based (I for one have been using the insanely easy but powerful filters in gmail). In fact, you should be encouraging people to use filters on your side - the more they do, the less unnecessary e-mails go out, and the less bandwidth you use.
There were some feeds which updated 10 times a day, and I really needed a daily digest for them.
This is a dream come true.
Cheers!!!
