ARRL has recently reported quite acceptable compatibility results in

I forget the details, 68 years old and suffering from occasional 'old
timers disease', but the info should be available from ARRL.

It is possible that acceptable BPL technology has arrived!

No.

It's acceptable to the ARRL because they "notch out" the ham bands. This
means that it interfers with everyone except ham radio operators so they
wash their hands of it.

What will happen is as people complain about interference from BPL,
operators will move the frequencies it uses to avoid the complaints.
If they bother at all, an engineer will take a portable radio to
the site, pull up the antenna and listen. If he does not hear English,
he'll log that there is nothing to prevent them moving the notch
there and that frequency will be used.

Since HF propigation changes from hour to hour and day to day, a
frequency can still be in use but he wouldn't notice it. Eventually due
to demand and no one complaining too loudly all frequencies in the HF
band will be in use. By that time no one will listen to the few hams
that complain.

My experience with a starting a Google boycott shows me that hams really
don't care. The operator of one very popular site dedicate to ham radio
and I discussed it and he said that they could not afford to eliminate
the "Ads by Google" and gave me a polite rationalization of why they
should do nothing.

This is called the boiled lobster effect. A lobster placed in a pot of
cold water will be happy for the change. As the pot gets warmer the
lobster gets drowsy. By the time the water gets hot enough to cook it,
the lobster has been lulled into oblivion. That's what will happen
with BPL.

It's already started.

You should have boycotted Google while you could, now Google supported
BPL is in action. Time is running out on worldwide radio communication.
