re: They have a common interest
From my inside knowledge, much of the common interest involves somehow keeping the government from stomping in and enthusiastically ripping the guts out of a fledgling industry. There's already a bureaucracy in place, and when you have bureaucrats, they have to justify their existence by doing something, whether it's actually needed or not.
Unlike the internet, which became a fact on the ground before the government had time to come in and "help," Washington is already into this with both hands. It's going to be tricky.
