Yes we do. In fact, we hitched them together for a 20 mile ride on Friday but, after about 20 yards, the quick link for the rear chain came disconnected and jammed in the derailleur. Made me real grouchy! I'm over it now.

One of the things I wanted to try out is how well we can communicate on the two Ketts linked together. I know 2 different DF tandem teams who own wired "Tandem Talk" innercoms, but neither likes them brecause you have to remember to connect and disconnect every time that you get on or off the bike. If we have trouble talking while we're riding, I guess that we'll have to try the more expensive, wireless version. I'm reserving some of Mrs. Grouch's Greenspeed money for that.
