There was talk with the pluto system to have multi-cores, ie one at home and one in your holiday home. Dont think that it every got to a working state,
You could setup another core, and add all the devices to it, then stop the dcrouter running on that machine and point it to the ip address of your otehr core, sisnce normally uses 127.0.0.1 to point to the dcrouter.
I might be worth trying using vmware as a test to see if its possible. I've got a quirte week this week, so will see if i can set up a proof of concept.
