The N800 doesn't use bluetooth to communicate as far as I know, but it does support "follow me" by manually selecting another room (like all orbiters).
The problem with "automatic" follow me (when using bluetooth devices) is that you'll need Class 3 bluetooth dongles, these are short-range/low power, and seem to be impossible to find nowadays. The other classes have such a long range that the device won't be out of range and reconnect until you're well outside of your house.
