I've been doing something like that (try to get people to make regular payments) with CodeMirror, in the form of selling commercial support. I've found it hard to get people to continue to pay, and a major time drain to keep track of all the paperwork involved. A crowd funder driven by a short hype is simply much easier to manage.
