Even better if some product came onto the market, that used wideband powerline communications for its functioning, and practically everyone's got one. I think some electric car chargers might do so in the future. That would not go down well with amateurs, at all! When everyone down the street would have, in effect, legal jammers.
MaxLinear have some nice ones, complete with datasheet, it also works in MIMO mode, not for just powerline but pretty much anywhere.
Update: I think solar inverters are causing big problems here already, so it's only a matter of time now as they become increasingly popular. So we can kiss those amateur radio enthusiasts and their utterly draconian punishments goodbye in the long term.
It's been like this already, for quite some time (!), at lest here in the UK, VDSL2 to thank for that:

So it's already being jammed, with the noise floor going up, although not to the point of being unusable.
