Well, I wrote an Squeak-based driver for X10 wireless remotes...that's
not IR though, it's RF. And actually, the only thing I had to worry about
was serial communications in the end. :)

Oh, I see...you're going in the opposite direction I am. :) My driver
is for receiving signals (controlling Squeak via remote)...yours would be
for sending IR signals, correct?
I had considered a 'quick and dirty' way of doing this on my iPaq via Squeak
at one time. If you're in Linux-land, there are a bunch of command-line
tools for manipulating the IR port...conceivably you could hack something
together with OSProcess to do it. Of course, that's not nearly as portable
as a primitive.
