How to turn on a light across a room without a wire?

[callmevlad@xxxxxxxxx]

I live in an apartment (so messing with the in-wall fixtures is out of
the question), and I have 2 lamps in my living room.  One of the lamps
is controlled by a switch on one side of the room ... flip the switch,
and there's light.  The other one, however, we have to turn on by hand
because it's across the room and there is no way to wire the two lamps
to be on the same outlet.

Is there a solution out there which will help me set it up so that the
light switch I have now (I don't want to add another switch) can
control both lights?

Is there a gadget that will hook up to the outlet which is currently
controlled by the wall switch (between the outlet and the lamp), and
somehow send a signal (either via IR or the power lines) to another
"gadget" that is set up between the second lamp and an always-on
outlet? This way, when I flip the switch, both lights come on.

Anyone have any suggestions? I'm a newbie at this stuff, so any
pointers will be appreciated.
