Well, its works quite well.. we did a test back in April on a network, and one node on the network (mine) doing the video. Regular PC's, mine doing loads of other stuff while the nodes in the network spam each other. Video is below:

One node was placed in Denmark, another in the UK. So, beta test, before recent database (and other) optimizations, test network across the internet. No cheating, no preload into ram. Just a straight up test to see the status at that time.
