Wicked Lester:
You would neet to get a cheap network switch, like this one
http://svp.co.uk/products-solo.php?p...24&ci_sku=4788 plus one extra ethernet cable.
You would plug the network cable from your modem into one of the switch ethernet ports. You'd then run a network cable from another switch port to your PC. You would then run a network cable from a switch port to the homeplug, plugged into the mains.
On the Xbox you would run a network cable from the xbox ethernet port to another homeplug, plugged into the mains. Job done
This review from dabs might help explain a little clearer...

Rarely have expectations been exceeded by so much.
I live in an apartment and wanted to share my broadband connection in one room with a PC in the spare room. Our wireless router works well, but I wanted the increased speed + reliability of a wired network. Read about the concept of “Powerline” devices in PCW, but wasn't sure.
However, given the (very) low price of this device I thought it was worth a try. Boy was I right.
The box contains two Ethernet cables; two power cords; two very small black boxes (c. 10cm x 10cm); a CD.
My experience:
Plug power and Ethernet cable into one of the black boxes; plug power cable into wall; plug Ethernet cable into spare slot on broadband router.
Repeat procedure with other black box, plugging Ethernet cable into PC.
Stick CD in PC, install software. No config necessary.
In 5 minutes, a high speed wired network in my apartment. For less than £40.
Phenomenal.
