Is it possible to get it to work with Hamachi? Hamachi creates virtual private LANs over the internet. So even if my computers and n800 are at different WIFI points they can still communicate in a networked liked environment.

How does mceguru currently conduct scanning? Maybe, have it so you could input the IP address (well in this case the Hamachi IP which doesn't change unless you ask it to) to direct mceguru towards Vista's mceguru with the Media Center?
