The Pypy project is funding the developments of new features this way 
(http://pypy.org/ - right side of the page, there are proposals, how 
much they cost to implement, and how much was donated). There must be 
others, I am just more aware of that one.

A potential difficulty is that all of R-core is possibly already funded 
(tenure positions in the academia, I'd guess) and might be moderately 
sensitive to the fact that a given feature should be implemented because 
people are paying to see it appear.
