After playing around with ways to
grow corners and keep them sharp I decided to try something with paths.
I wrote this initial script:
http://www.silent9.com/incoming/scripts/offset_path.scmOnce installed, right click on a path (only works with the path nodes - so curves don't work) in the paths dialog, and select "Offset Path..."
It will create a new path, with all the nodes offset in a way that the new path lines are all parallel and offset those of the original:

It will do some funky things (like invert path segments) if the offset calculation crosses itself.
