I'm in on this one, too! I can only invest a little money, and no knowledge, but add lots of enthusiasm also.
My son-in-law is a programmer, and a couple of years ago when we saw what was starting to happen with ATX, I asked him about trying to put together a Linux-based tax program, but he couldn't find people with both tax and computer know-how. And I think it was a bit intimidating, trying to go up against the big guys. But we can do it.
