Sorry to hijack the thread. I've been considering developing a few different products to broaden my product line so it isn't so WISP focused. One of the things I've looked at is a terminal server device since the existing ones seem so rediculous for the price.
BUT.. to meet the price target I'd want to hit, cellular connectivity would be out of the question, due to the excessive cost of the testing that the cellular networks require to permit connection to their network. This is probably why the existing products which have cellular connectivity cost so much. I was sort of under the impression that it was pretty typical for out of band cellular access to use one of the off the shelf wireless routers/hotspots to provide management-only ip connectivity. That way, you can connect to the management interface on every device. Is this not the case?
