I would definately be interested in doing something like this as well, with a DVR, DVD, Home Theater System and especially now since I just got a new PC with Vista Prem, using Windows Media Center and am using my Xbox 360 as a Media Extender, it would be great to be able to program my N800 as a Universal Remote with that plug-in IR attachment shown in that article, rather then shelling out another $150-$300 on up for a Logitech or similar LCD'd programmable remote device.
