<pre wrap="">2) More complex, a question about polygons. I have maps with large numbers
of polygons with shared boundaries. Is there any way to count the number of

You need to use two vector layers (v.category) and v.to.db. See its manual
page for an example (or, in the new GRASS book, see
"6.5.9 Length of common polygon boundaries" for a similar task).
