Hi, i don't have the answer for your question, but maybe you can ask this also on www.girder.nl. This is an site about a freeware application where you can control your pc with your remote control. I do not know if it is also for an laptop irport and if there is an add-on for what you want.
Even if you do not find your answer it is a nice site for ir freaks to have a look at.

Good Luck

Rob
