Wow, great use case. I wonder if EtherPad can focus on such a niche and charge for it (with other relevant features).

They actually know about the use case: it's one of their 5 suggested use cases: http://etherpad.com/ep/about/product#uses5

But you're right, marketing specifically to software shops could be a good way to make a profit.
