Thank you for all your answers.  This has helped me a lot.  I think I will 
buy one of those Keyspan PDA devices.

I´ve been using the Irman for some time now and I´m quite happy about it.  
I´m using it using a driver written by someone on the net.  I haven´t looked 
at the sourcecode yet, but I would presume that the Irman does the decoding 
itself, so I don´t think that that would pose a problem.  I think I will just 
try it and I´ll let you guys now if it works.

And BTW, since I´m using the Irman in an application that I´ve written, I 
would rather not like to change IR devices.  I´m trying to stick to the Irman 
(so you don´t have to speed up the development of the driver for me ;)

Cu,
Bart De Win.
