I absolutely love your idea. I think the best thing about it is that it can be dead-simple or ridiculously complex, with dividends and whatnot, but the idea works for so many projects.
An added thought could be sponsoring modules that don't exist yet to spur on their development, maybe your company uses some open source product that supports a bunch of file formats but not .xyz, you could donate to a speculative XYZ Module and then everyone benefits and the developers have an incentive to write it.
