Interesting one this, DN.
Most global power companies have been experimenting with using their transmission line for a wide range of data transfer.
In France, my new "computerised" meter is turned to cheap rate at midnight and off at 07.00AM by a pulse sent down the line.
One area the companies are looking seriously at, is remote reading of their meters: think of the cash they will save!
In the UK, some carriers are already using their lines for multi-plexed landline and data.
Privacy? Solved by the correct layers of encryption. Spurious emission of RF? Well, high frequency high voltage mains transmission systems already emit RF interference.
With the spectrum flooded by all sorts of stuff already, can't see how this could make much difference!
3G mobile phones are the biggest future problem: particularly for those who seem to always have one glued to their ear!
Brains will be fried in months!
