A wall-wart is simply one of these:

(apologies for the French site - it's the quickest one I found with
the best picture)

Relays are these things:

And Ian posted the link to the neat current sensor for Comfort, it's a
nice solution and would seem to fit your requirement.

What's thw wireless bridge connected to?
Can you use it's connected device to turn it on & off? Although your
original plan for X10 was fine in theory (i.e. having Comfort turn it
on/off).

One a side note, can I ask what you think of your Synology box...a
friend was looking at them but couldn't find much user feedback.

HTH,

Tim.
