As far as a motor is concerned I guess 'producing an orgy of annoying beeps'
is pretty intelligent :)

If you're not afraid to use non-lego technology you might take a look at the
Velleman K8000 kit, the 'Computer Interface Board'.
It's constantly connected to the PC thru RS232, though velleman also sells
kits to control 'things' by IR.
It has 16 'digital' outputs (one resistor and you got TTL), 8 AD Ports, 4
DA ports AND an I2C interface. It comes with source code (C++, Visual basic)
and is not to hard to build (lots of soldering though).
Their kits also include temperature sensors, liquid sensors, stepper motors
(!), motion sensors, rotation sensors and a PIC, so it is acually possible
to build an RCX out of it.
Though it would be far bigger in size, it would have far more ports and an
I2C bus. Besides, it's got more blinkin' lights, you gotta have blinkin'
lights ;)
Though I'm using it for different purposes I have shot some pictures of the
kit:

It does :)

Programming isn't that difficult, it's mostly a logic thing. Kids pick up on
that a lot faster then 'we adults' think.
An RCX is basically the same to a kid as those wooden boxes with different
shaped holes and blocks. It's just fitting the blocks in the correct holes
in a clever way and off you go..
