Full on X10 using the PLC part might not work but Dave's suggestion of RF
hints at a solution.

Just pick up an RR501 and a couple of KR22a or KR19A remotes from EBay.
Then modify the RR501 a bit by 1. extending the antenna to make it a true
1/4 wave or 1/2 wave length and 2. (optional) desolder the receptacle and
plug and hard wire it to your incoming power and your light (or skip this
step and plug it into a receptacle in the outhouse and use a plug-in lamp
for the light).

You could probably poke around on Ido's website a bit and figure out how
to disable the PLC xmit/rcv circuitry as well if you're worried that
signals from the RR501 might cause other havoc due to the MSW-inverter.

Here's a google cache of a page from the site dealing with RF range
improvements:

Of course, before modifying anything I would just plug it in and test it
to see how far away you can get and make it work. In an area with little
stray RF you might not need to modify anything.
