This is the best proposal so far. But it still nags me that this gives 
proprietary software vendors a free lunch when they are actually quite 
willing to pay, while the open source movement has so many financing 
problems. Here are some low-hanging fruits that we are not picking 
because we cannot agree how to organize it.

This would in reality be a one man organization doing all the 
administration work, and everybody would have to trust me. And what 
would happen if I die or become unable to continue? It would also get me 
into tax problems.
