New service idea, a POST endpoint that accepts and stores any data, but the path is a token (either a guid or a random word song) that's got various validity checks (can only be used n times, max (and min?) file size, expected content type, source ip, that kind of thing). File gets saved and only the logged in user who created the token can access it.

specific use case is too give Google somewhere to post the data from husbands food diary spreadsheet export, but might be useful to have laying about.
