In fact, there might be future regulations that implement the very thing you are talking about. Startup signs a contract with the government (instead of paying ISP) saying, "I promise not to use this amount of bandwidth." It could even be a universal number. If they do go over that. FCC will fine them. Big Time! I actually see this legislation coming sooner rather than later.
Either way, everyone is halting right now because all or most of their current contracts are now up for review and no one knows what could happen, change, or be implemented/ignored.
