Very interesting, thanks! The VM notion came from the way github distributes their enterprise offering--you're saying most large companies wouldn't like that?

Very interesting, thanks! The VM notion came from the way github distributes their enterprise offering--you're saying most large companies wouldn't like that? What if the DB tier isn't standard SQL? Will that be a barrier? (I assume the receiving IT dept doesn't get involved until very late in/after the sales process, but presumably they could still put a wrench in things if they find the deployment too complex.)
