So, I don't really see the possibility of having nodes on a network

I like to do something like "zonal statistics" on vector areas. Not with
rasters, but with vectors inside. That means eg:
"length of all roads of a kind for every area". Or: "longest road on
that area in an network of roads".
Maybe there is a possibility to "cut out" line features on the border of
areas?
v.overlay operator=and: the result gives you an attribute table
combining both original attribute tables and thus allows easy summary
statistics through SQL queries.
