There was talk of this some time ago on one of the GRASS mailing lists,
try searching the archives for the answer. (maybe a year ago?)

from memory the solution was something like:

v.to.db option=length

dividing that length by two and adding that value to a new column in the
attribute table of the lines with db.execute.

Use one of the v.net.* modules (v.net.path ?? v.distance ??) to
get/place points at that distance along each line from the start of
the line.



good luck,
Hamish
