The control interface would have to lease on a first come first served basis with a timeout, or else you get 20 people trying to go 20 different ways.

Hey guys. I was going through some old site code while doing a major recode and rebuild, when I found some code I used earlier on in the year that I want to tidy up and put out there for the community. The story is that I was moving from far north-west queensland, australia to tasmania, australia. A roadtrip of about 4000 Km. I wanted to be able to post to my blog en-route and provide a map so that my family and friends could see where I was at. The first thing was a simple little php script that logged into a pop3 mailbox and parsed a email into a blog post. I also had a similar script that parsed and stored a gps location. Being kinda poor, owning an old phone with no wap and sms' being so cheap, I found a free sms to email gateway. This allowed me to post my blogs as well as update my location in a database. The second piece of code took the gps points out of a route (from .... to ....) in a google maps kml file (the compressed file in a kmz file) and drew them using the image functions in php. I also drew some other kml files into the image to give me state borders, etc. I also drew some city points and names, giving a result something like this:
