Thanks all, good comment.

Great shame we haven't greater bandwidth for WiFi or something broadband
spread-spectrum so that we could do away with all these pesky cumbersome
wires... Then again, the encryption and signal processing could well
require a very un-green extra power station if widely used!


The main motivation is to keep multiple devices guaranteed separate on a
wired network to thwart at least one malware vector, and also to FORCE
file sharing to be possible only by means of a central server.

Doing that without the need for VLANs looks very nicely plausible ;-)


Thanks,
Martin
