Comment:

 ah, calculating the great circle distance between every node of a polyline
 could be rather computationally expensive, but it is possible if you don't
 mind the wait.

 to clarify: does the current version report decimal degrees (aka garbage)
 for v.distance in a lat/lon location? If so it at least deserves a
 warning, and in general a fatal error is better than plausible but
 actually meaningless results.
