[Icecast] publishing an icecast stream

[Dave]

Hello,
    I'd like to publish an icecast stream that i'm streaming from my server. 
I know i can do this by uncommenting the appropriate lines in my icecast 
config file, but i've got some questions. I'm running icecast2 and ices0 and 
this is an mp3 stream generated from a filebased playlist. First i've looked 
over some of the streams on icecast.org and i was wondering for the 
metadata, and descriptions, how verbose should i be or is there a 
requirement for that? Second, i'd like to offer two simultaneous streams, 
same content, one for dialup users, one for broadband, this is a feature 
i've never got to work to my satisfaction, it breaks up or the dialup audio 
quality just isn't right. And some streams showed what they were currently 
playing, how would i implement that?
Thanks.
Dave.
