Icecast - Feb 2005 - Limiting mountpoints

Hi List,

I'm pretty new to IceCast and I've got a question,

Is it possible to limit the amount and types of streams (mountpoints) a 
user creates?

Scenario:
I've got several users (say 10), that I want to be able to stream 
through my server.  But to limit the bandwith costs I'd like to limit 
the amount of data they stream.
- The mount specific options will allow me to 'reserve' specific 
mountpoints for each user (by way of user/password), but is there a 
directive that prevents them from creating a new mountpoint? (as they 
are created on-the-fly by default).  The only way I can easily see is 
launching a seperate server for each user and limiting the sources of 
each server to 1.
- Are there directives (either server-wide or mount-specific) that limit 
the type of stream (bitrate, encoding etc) that sources can supply?

I've checked the docs, and read through the last few months of 
maillinglist archive, but I couldn't find a reference to my questions.

Any help/tips are very much appreciated!

Well, if you create a specific mount section for each user, with its own 
password (and username if their streamer supports that), the only way they 
can create any other mountpoints is if they know the global source 
password.  So if you keep that to yourself and make sure each user has 
their own password, they should all be limited to the one mountpoint for 
which they have the correct password.

No.  I've seen places like mediacast which charge according to these specs, 
but don't know how they enforce it (maybe someone from there is on the 
list).
