A while ago a built my own code to display my latest location on Navizon (a GPS, WiFi and Celltower location service that runs on Windows Mobile, Nokia and iPhones)

While rolling my own gave me a fair amount of flexibility it struck me as fairly inefficient - all it's doing is grabbing an XML feed with location and displaying it on a map.

Since my first quick play with Popfly I've not really played around with the mashup service, but I had some idle time this morning and wondered what I could do to solve the same problem that way...

Well, 20 minutes later the Navizon + Virtual Earth mashup powered by Popfly was built (you just need to change the Navizon ID to show you instead of defaulting to me - if you sign up to Navizon to try this don't forget my referral code: 5E585D5B5A!)

This mashup refreshes every 30 seconds, pulling the location data from the Navizon XML feed and updates the pushpin with the username and the last seen data.

I'd like to find a way to tweak it so that it remembers the map zoom level for a particular user and makes it easier to change the userid for other folks when they're embedding the mashup (my previous attempt allows you to send userid, width and height of the map as parameters) ... maybe if I have some free time I'll play some more ;)
