BTW- the cable-pull-multipliers (travel agent, etc) are dangerous. Under certain conditions they can cause the cable to break.
This is true. The conventional stranded cables are prone to strand breakage at sharp bends such as the Travel Agent induces. Braided cables are more resistant to this due to their flexibility, but also seem more stretchy IMHO. And the Travel Agent already induces a little extra "mush" into the system.
For the record, Shimano's rear shifting is pretty standardized (possible exception: 2003 XTR), so anything that works with a bar-end rear shifter should work with STI, whether it's officially MTB or road. The front shifting is not quite so well ironed out, so I applaud the choice of bar-end shifters.
