I'm running a geocaching wiki, where I'm hacking on an extension for displaying GPS track files on a Google map. I'm considering if it's worth the trouble of packing it up in a form that's easy to use for others, or if I can skip the niceities, and just make it work for my purposes.
Displaying GPS tracks seem like a very narrow application, hence my question. If anyone would be interested, please let me know. In that case, I'd also like to hear what would be useable.
