I was interested in this myself, so I took my Raleigh Twenty to my LBS and tried my SRAM Dual Drive with 105 STI shifters...it worked perfectly after a little adjustment. On a negative note, I have read that the internal gears don't like friction shifters, so just make sure you can get bar cons with indexed 3 speed front shifters...if they exist. I've only been able to find friction style front shifters(of the bar con variety), but what do I know?
Another thing you might be interested in is that when I climb in my "small ring", I feel like I'm losing efficiency because of the internal gearing. It may actually be only a minimal mechanical loss, but I do feel it, and that is REALLY no fun when you are climbing. I just thought you might want to know, since you are planning on touring. I'm thinking of changing over to a double crank and losing the internal gears altogether.
