I'm not sure if I remember correctly, but I think zinglebarb has experience of this kind of kit.

When I looked into it I thought the units were quite expensive, but it seemed a viable alternative to a wireless setup.

In its simplest configuration it would work to 'relay' a signal from a pc, say upstairs, to a cable modem downstairs, via the house mains, with no problem.

I'm not sure about how fast it is, though???
