#4.

It's terribly dependent on hardware and the linux kernel and how
they interact.  It's a kludge that happens to work with Linux.  I
have doubts about it working with BSD.  You'd need a new kludge.
Or a better way.

For the commercial box (that you'd need to deal with software on)
there are devices like this:

A little google for: "serial infrared VCR" turned up about 50
million hits.

Better way to handle the whole IR thing?
If you can even remove the carrier from the signal (40khz, not
36khz), you win.  That's a pretty straightforward circuit.  For
reading in the data stream and presenting it, single chip CPUs
(PIC, etc) are almost ideal for this (if overpowered).  compare
this with treating your large box as a single user machine servicing
a serial port.

But lirc is unlikely on BSD.
