Yes - I can control the RCX from my SONY Television remote (which is
a programmable one) by 'teaching' it key commands from the Lego Remote - so
if your PDA can act like a learning remote - it can drive the RCX and Scout
bricks.

Yep - but some PDA's don't have the right kind of IR port - some have
ONLY an irDA port - and no CIR (which is the kind that TV's and RCX's use).
I've heard of people having some success with dirty low-level trickery and
the irDA port - but I'm not sure how good that turns out to be.

Yes.
A PDA is (IMHO) the natural way to go in getting better on-board
intelligence and higher speed communications from a *small* robot.
Whether you can kludge together some kind of motor/sensor driver
for your PDA - or whether the RCX takes on that role is an open
question. Either will work - I think it just depends on what you
want to tinker with!
