One of the best things we can in defense of the HF spectrum (ham, military, commercial, etc.) 
is to operate our amateur HF transmitters at full legal power in the vicinity of active BPL
systems.  BPL uses adaptive signaling that changes data rate to accommodate changes in the
line quality, something like a V.92 modem that adjusts its data rate as phone line noise
levels change.  And we'll still be legal, IMHO.

Carey, filtering out broadband signals like BPL can be done with DSP, but it's not a cheap date.
