I don't think that's a good idea. IRDA is now also being dropped from
laptops. My MSI wind doesn't have an IRDA port. Most functionality that
IRDA provided is now replaced my bluetooth.

Nevermind the fact that VERY few desktop systems have an IRDA port. 

While not as dead as RS-232, IRDA isn't too far behind IMHO.
