I do. In fact I use the Beo1 to control my AppleTV via Lintronic. It works really well. The only function missing for AppleTV is Fast Scroll. I used it previously to control a DLO Ipod Dock.
I think the design idea behind the Apple Remote is similar to the Beo1, but B&O has a much more sophisticated design.
BTW, Beo1 only works with a certain release of the firmware. So if you have not updated your Lintronic in a while, you may need to do so. Check with the Lintronic site to be sure you're up to date.
