Why do powerline designers seem to ignore the fact that it might be useful to keep the power socket available for use for powering - oh, I don't know - THE COMPUTER when designing the products??

I don't think so. When the idea was first tried the biggest problem was that every substation transformer has to be bypassed at the frequency used. A transformer that's good at 50 hz is not good at several megahertz.. There are a lot of transformers about, meanwhile the fibre-optic network is continuing to spread, along with cable.

RE: Comments so far....
I've got the 85mbps powerplugs and they blow the water out of any wireless connection I've tried for both reliability and speed i.e. pretty much same as 100mbit ethernet.
For those of us that don't fancy rewiring our entire households with ethernet and fibre-optic networks to go along side our existing electricity cables, powerline networking technology is an amazing solution.
John Murgatrod - think ur living in the dark ages talking about transformers interfering with it...
Some of u have got the wrong end of the stick, this is a local networking technology, i.e. for home lans etc, not so your ISP can feed u broadband over a powerline.
...wire is cheaper, and works quite nicely. It is not subject to problems that surge protectors and filters (common in computer installations) will cause. To me these devices are a waste of money.

is the point. all of the HPA vendors have roadmaps beyond 200Mbps, Gigle for one have already announced that they will release a product with a 1Gbps PHY next year. I guess DS2 have to announce something given the IEEE decision (that means they will have to redesign completely to comply to the upcoming IEEE standard...).
have done a lot of testing of HPA and DS2 products - and the HPA will give a lot more bandwidth than the DS2 in the "real world", the DS2 is very sensitive to electrical noise.
correct, the signal will not pass through transformers - this is not an access technology, it's a home networking technology.
no, i don't work for Gigle or any other HPA silicon vendor, just know something about it...

PSU with ethernet built in anyone?
not sure how they will have 400Mbps "early next year" #

not sure how they will have 400Mbps "early next year" when their chipset supplier was quoted by the Reg a couple of weeks ago thus:
"It expects such an application to be in demand "from 2009 onwards", and that's when it expects to get 400Mbps technology into powerline Ethernet adaptors."
So they will release products using a new chipset that their chipset supplier hasn't released yet?

Done it, been there. Netgear do a power supply for their routers which also acts as a powerline adapter, I have one running as I type and it works just fine.
@Do u guys know what ur talking about???
Agree with all you say my network of 5 runs much better on a powerline than on wireless where I had problems with drop outs and poor reception due to thick walls and concrete floors, not everone wants to or can run cables all over the house, my landlord would go nuts if I pinned cables to all the skirting boards or pulled up the fitted carpets.

I can see it now! #
