Definitely worth looking at the Things' blog: http://blog.tandemthings.com/
They used their Tandem for RAAM, which has some big long descents on it (especially in Colorado) and they've done a whole bunch of other rides with big descents.
They've got a Paketa tandem (magnesium) with Di2 plus some other fancy bits (such as an adapted drivetrain so that the timing chain is on the same side of the drive chain, so there's less power put through the frame laterally and so less frame flex).
Don't even want to think about the cost though.
