For your list.  Apologies on my late reply, my Powerbook went in
for repair....

One 7 June, the IEEE Power Engineering Society held a small joint
meeting run by the IEEE Standards Group.  The topic was what if
anything should the IEEE get involved with in BPL.  Information is
available on that meeting at:

    <http://grouper.ieee.org/groups/bpl/>

Please note the next installment of that meeting is this coming
week at IEEE headquarters in Piscataway, NJ.  Details are available
at the above URL.

At the 7 June meeting, the attendees broke down into several common
clusters of interest:

   + HomePlug / BPL manufacturers
   + Interfering emissions concerned folks and organizations
   + IEEE Power safety standards
   + Others

The existing manufactures are of a mind that everything is go and
they want to deploy 10's of thousands of these and more asap and
get them into consumer products asap.

The emissions centered folks are saying that nothing should go
forward until there is a common way to measure emissions, interference
caused by BPL, and standards for acceptable performance. My opinion
is that if power lines can't be tamed, then don't go there.

The power safety folks from IEEE are saying that if you are going
to hook up anything to low and medium voltage power lines, you got
to have standards for safety and equipment so people don't get killed.

Needless to say, I'm in the camp of emissions and interference control.
We here at Broadband Physics, believe that OFDM is not the way to
go for BPL and can show why our SDM is much better.  However, one small
shameless plug amongst the rise of the existing BPL swell and the
call for more gadgets for politicians.

Not sure what the IEEE will end up doing.  But if you want to get
involved, get to the next meeting.
