This is a great feature with a lot of potential. I'd like to be able to display tracks (both current and archived) for a selected user. I'd also like to be able to force the map parameters to defaults like satellite view, a certain zoom level, etc.
I had extended a code snippet that you published with the old "buddy tracker" into a tool for a blog that allowed viewers to see where a sailboat was in real time, but also to review old tracks. It centered the main map at a relatively high zoom, and had an inset with a lower zoom level (sort of an overview to orient. In any event, it would be great if publish could become that extensible.
Alternatively, if someone could point me at how to pull the same data from my gpsgate server as I used to from buddy tracker, I'll just update my old code. THis is the data source link I had been using:
