near the time the metadata is received from the source, or every so many 
  seconds, whichever happens sooner.

The automatic update interval can be returned to icecast after each 
request (originally it was only the add). It is directory server 
specific so whoever runs the service can decide.

personally I would use a packet sniffer

The information is passed via POST not GET if that matters.
