I am hoping to find a utility to extract vpk files so that I can look into them for zone information. The reason why is because I'd like to be able to generate maps based on the actual zone data, complete with textured topography and low detail wireframe buildings.
This idea is inspired by my old DAoC days, where I used a Python script written by Oliver Jowett of the late randomly.org to generate map images. Since then, it seems that someone has made a GUI for the script, and you can check out some screenshots of what I mean here:

I think I will look into the python version of this, and see if it could be ported to use different types of data, but what we really need is to crack the vpk files, and figure out the data format of the zones.
Anyhow, this is a related subject that I wanted to put out there, but I don't expect it to happen anytime soon.
