Blocking GoToMyPC

What is the easiest way to block GoToMyPC? I do not want employees either working on their home machines from work, or opening up the network by bypassing the firewall. I think from reading GoToMyPC's website the remote machine must login into one of the servers, then the client connect to the GoToMyPC server and the server relays commands to the remote machine. Also I think I read that GoToMyPC uses HTTP and other protocols that normally the firewall allows through. One idea that we had was to put a phony DNS entry into our DNS server for the GoToMyPC domain, to send that traffic to a non-existent IP on our network. Would this work? What would be the major problems with it? What about disallowing access to any ip that on a reverse DNS lookup falls into the GoToMyPC domain?
