easy way to query users and channel

Ice/DBus, Web-Interfaces, Management tools

is there an easy way to query which channel are on a mumble server an which clients are in which channels ?

i dont mean from localhost but over the internet

You'd use Ice for that as well.
Or you can do something like this ... p?f=7&t=41 (little self advertisment :D).
