I read that there is a device that allows you to set
up a comm network using your electrical outlets. Anyone
know where to get this?

Thanks.

Netgear makes a bunch of those turds.

Perhaps you've gleaned from my tone that I'm not impressed by those
devices. It may be that the XE102s are a particularily bad example of
that technology, or that I had a bad batch, but I found them to be very
tempermental.

Certain bridges would only seem to work in certain sockets, and a number
of them would not work for any significant period of time without a
reset. At first I thought it might be the circuitry of the house, as it
had experience a number of remodels, but it turned out the bridges
behaved just as badly in a completely different environment.

It's a bit of a pain, but I still think it's worth stringing Ethernet
lines throughout your house. Hopefully you already have some cable tv
lines run, and you can just buy some new double-duty faceplates to
expose your existing cable, and newly strung Ethernet. Run it all back
to where the phone and cable lines make access into your house. Make
sure you buy high quality lines.

Something like this ?

Homeplug - networking via signals carried over AC wiring.
http://www.homeplug.org/en/products/products.asp

Homeplug supports some kind of encryption (for signals going
over the power lines)
http://en.wikipedia.org/wiki/HomePlug

Ethernet to Powerline bridge (router to wall plug):

USB to Powerline adapter (computer to wall plug):
http://www.linksys.com/servlet/Sate...876218&pagename=Linksys/Common/VisitorWrapper

This Ethernet to Homeplug bridge mentions 56DES for encryption.
So that must be the encryption method.

And this one mentions "85Mbps" operation:

HomePNA - networking via signals carried over phone wiring.
Two versions - 1Mbps and 10Mbps.

One thing I don't know about this technology, is whether a bridge is
needed between phases. With North American home wiring, you've got
two phases for 115V wiring. A HomePlug plugged to one AC outlet, pumps
the data signal out to the pole transformer, thru the windings,
and back to the house. Now, what I'd be curious about, is whether
there are any "AC coupling" devices to make the path taken, be
only in the house.

OK, according to this, they didn't have problems with the two phases.
But they did have other problems. Looks like voodoo... Don't
switch on your vacuum cleaner :-) And stick with one brand, for
all your interfaces.

Also, it could be that the HomePlug AV (85mbps) version, is a bit
more robust than the original 14Mbps variety. This is another
example of a HomePlug AV product, at a reasonable price.

ZyXEL PL-100 85Mbps Powerline Ethernet Adapter - Retail $64

Another thing to note about the technology, is it is CSMA/CD and
a shared media. The 85mbps is shared by all the computers using
the power lines to send data. Not that this makes it inferior.
And it won't be an issue if surfing from the Internet.

So, come on, Bob, test this **** for us :-)

I'm a bit curious as to how applications trigger
the QOS feature.

P.S. **** = fine product
