Mumble Link for node tracking, etc.
Great idea, but unfortunately I’m not sure this is possible right now due to the Megaserver setup. As far as I know, there’s no way of knowing which megaserver “instance” a player is on, and I would expect that things like node locations would be different for different “instances” of a map. If the API is ever updated to communicate that information, this would work just fine.

We have already an app like this: https://forum-en.gw2archive.eu/forum/community/api/Gw2-Location-Tracker/first#post2379754
Since the code is all open source it’s completely up to you how you use the data. The only problem might be the new Megaserver setup – i haven’t tested the app with that, so i don’t know how reliable the shard_id is.
