There is more meanwhile:
- It's also used by v.extrude [1].
- I have added faces support to v.out.vtk yesterday.

Would you mind to tell us where you found it so that we can
update? In fact it's not too outdated, but could be written
a bit better.

Yes:
http://grass.itc.it//devel/roadmap.php
Additionally:
- get grassuser mailing list from Baylor to grass.itc.it
(to have all main lists here)
- discuss and use CMS (content management system) for GRASS
web site to enable more people to contribute
- form GRASS Project Steering Commitee in order to formalize
the development team
- discuss and get GRASS into OSGeo Foundation incubator
- have more GRASS meetings or GRASS hacking sessions :-)
