map of tor routers

["Bryan Fordham" <bfordham@xxxxxxxxx>]

I've taken up the task creating a map of tor routers. I have a test image up at http://socialistsushi.com/tor.png

So far I have a mapserver and data on tor routers in a postgis database, so I can produce images like the one above. Now that I've figured that out, I'd like some comments on how I plan to proceed.

Basically, my idea at this point is to query a directory server once a day, and check for running nodes. I'll add new nodes as they appear, and mark ones that are no longer running. I plan to also track if they are stable, and an exit node.

This way I'll be able to produce maps showing all nodes, all running exit nodes, and other combinations.

Is there a better way of tracking routers?
What else should I track?
Other comments?

I'm not using google maps so I can keep _javascript_ out. I'm using UMN MapServer (http://mapserver.gis.umn.edu/) for those who are interested in such things. I may do a nicer UI (_javascript_-enabled) for those who aren't worried about such things.

Thanks
