What kind of quality issues do you have?

You might want to experiment with the CVS version of darkice, which 
includes quality setting capalibities.

Is there a way to run multiple streams off of one Oddsock DSP with a single 
input as you can with the Shoutcast DSP or do you have to relay and have 
multiple copies of WinAMP with the DSP running multiple times?

Hi there, im wondering if anyone has any guidelines on things such as
max execution times, etc on functions like ices_perl_get_next.

Obviously, you don't want ANY execution time really per se, but, as a
test I had ices go and do an sql call that took ~2 seconds before
returning a track file. Which resulted in a segfault. (output at bottom)

Also - as a side note, for anyone who doesn't realize - any modules you
write must return 1. Not just the functions, but for the module itself.

(example: ices.pm will not work as is. If you add a return 1; to the
bottom, it will return properly, and ices will start. (albeit broken -
you most likely don't have the default mp3 - but it will keep execing
next_track in a loop) If not, it complains about returning a null value
and wont start.)
