Probably most people are familiar by now with crowdfunding initiatives, most notably Kickstarter. There's actually a site called Offbeatr.com that focuses on adult projects, including instances of adult, freeware games that have been crowdfunded through the site. A third Legend of Queen Opala game appears to be approaching full funding within days of starting, despite setting an ambitious $30k target.
I would assume that the AIF community by itself is not likely so big (or at least so engaged) as to support such a funding model, and simple "donation" systems have never really worked out for AIF. Nonetheless big AIF projects are getting bigger (and rarer), and things may be changing in adult game freeware, so I wonder if Offbeatr will ever be relevant to AIF. What do you think?
