I think most guys would use a computer by the mount and a computer inside and connect using Remote Desktop or Team Viewer. Im not sure how you would go transmitting stuff that needs to be High Speed USB2. I'm not really up with that as I just use the above method and it works great.
Others may have tried before and have more experience. You need to be 100% sure that your gear is doing what it is supposed to and can have an emergency off switch.
