Mark Woodward might have more to say about this than me, but a cheap and
relatively quick way of turning a few things on and off is the parallel
port.  The hardware is dead simple.  Software for controlling 8 things
or less is pretty easy using the data pins, but you can get two or three
more with the status pins.  I have a book called "Parallel Port
Complete" you can borrow if you're interested.

I'm more into X10, which would work too. and allow remote operations.
