FCC is proposing rules to Broadcast over Power Lines (BPL) see-
http://www.arrl.org/news/stories/2004/03/18/100/?nc=1
Basically this will add radio "noise" in the 2MHz to 60MHz whereever there are powerlines (your house, etc...). Which means that IF you are able to still control your vehicle (air,land,water) you will have less range due to the increased noise.
We, in Amateur Radio, are expecting serious degradation to HF and VHF communications. I just thought you should be aware too.
FCC isn't really listening to Amateur Radio, FEMA, nor the fact that 6 other countries, like Japan, have tried and dumped BPL.
