Crosbie Fitch has been working on this sort of thing for a while. And recently some other projects that support different ways of funding projects have started gaining in popularity.
Kickstarter is best known in free culture and free software circles for funding Diaspora, but there are lots of other projects on there (I contributed towards the Mondo 2000 History Project for example). It’s an escrow or street performer protocol system where people promise to create or do something if contributors promise the right amount of funding.
Flattr is a micropayments service that allows you to add a donation button to blogs and other social media. I’ve started seeing this on blogs I read. There’s a flattr plugin for Android apps that might be a good way of getting funding from users of published free software.
VoDo is a peer-to-peer movie sharing
network (using Bittorrent) that allows you to sponsor the creators of
the work shared over the network.
These systems all offer ways of getting money in
exchange for artistic labour that are sorely needed. But they are all proprietary systems run by for-profit companies, so the
revolution will be monetized.
