I also didn't mean to sound like there hasn't been any work on this.
IMVHO, it would be nice to see more work done on this. (I know we've kind
of split on a tangent from Ernst's original query, but...)
I think shoe-horning one type of interaction to be used for another
(either using a manip technique for loco, or a loco technique for manip)
would be suboptimal. That said, using the same *device* for the two, and
including a mode-switch might be interesting, with some practice. It might
be interesting to use the non-preferred hand for some gesture-based
locomotion, while manipulating with the preferred hand. This would fit
into Guiard's notion of the non-preferred performing gross tasks, and the
preferred performing precise tasks.

Just babbling...
