Come to think about, this idea is actually fairly kick-ass (in theory).
Some problems, maybe you've already thought about these, just throwing these things out there:
1) We don't have many members (not much money circulating on here)
2) Out of those few members, not many are very wealthy (I'm only assuming)
3) Out of those members that even could donate, many don't want to and prefer free programs
4) How would we decide on a program that everyone wants and is willing to donate to?
