That's a very valid option, and we're giving it a lot of thought (come on board and think with us!)
Our business itself is open though, so anyone welcome to join us (no permission needed from anyone) and contribute to the code base, and gain equity.
As a member of bettermeans, you still can't take the code and run it elsewhere, but you do get full access to it in order to contribute to it.
So it's more 'shared' source, and 'open' business.
My sense is the wordpress business model works with very large numbers, and an already established community. Two things we don't have.
