check the mailing list archives, it is in there,
from memory it was like
v.to.db option=length
then use sql statement with length/2 to get half length and v.segment
(???) to travel down line to the 1/2 distance. There are a few modules
which do the v.segment thing, have a look at v.net.*, v.lrs.* too.
