raw XML is fine, easy to parse with PHP's SimpleXML extension. 
the tip about the mount specific credentials is helpful, thanks.
so i don't need to expose admin data in my scripts.

00ps: i've just crashed icecast with the above call, specifying a nonexistant
mount, i.e. http://127.0.0.1:8000/admin/listclients?mount=/not_on_air

is that a known bug or specific to my setup?

thx, uno
