You shouldn't have long to wait, now. The people behind iRed and irTrans have the solution you are looking for. When iRed 2.0 is out of beta shortly, you'll be able to control hardware with that software and irTrans, through a Mac computer. People who have used the 1.x version of iRed to control B&O are most pleased with the solution.
The 2.0 version of iRed will emulate the remote control buttons on the Touch surface -- which sounds pretty ideal. I'll be using mine to controll both B&O and non-B&O hardware.

Search the site for iRed and irTrans, and have a look at this site:

Thanks for the forecast Soundproof; what you suggest will be a boon to all B&O users!! The iRed software looks most promising. I'll follow up on that as well as the iRTrans ethernet for Mac. I really appreciate your thoughts and tips here. Have a great Boxing Day!! (Mine's just over as it's after midnight!!)

Cheers! 

Today iPod Touch 32GB available.

Tempting!!!! 

I'm only using my Touch to control the music and film playback at home, which means I won't need the 32GB one - but it's probably a good one to have if you plan to travel with the Touch. Mine spends its time being charged in my AudioPro, and I can also control it remotely while it's in that dock. If I didn't have a music centre I would probably want as much music on it as possible, though.

When I want to control my music centre the Touch is ready with a full charge and gives me two-way access to hundreds of GBs worth of lossless music.

Now that I can use the AppleTV as an AirTunes station, I mostly listen to iTunes through my stereo. In fact it's so good that even dad is impressed (difficult to do with technology) and is looking at getting some Airport Expresses for use around the house (in the kitchen and lounge). The iPod Touch would make a brilliant remote control...
