Because of the upstream bandwidth limitations I recommend that you
reconsider this requirement. As you have already discovered more then
800kbit/s upstream is going to cost money. Even 800kbit/s on DSL is
optomistic and likely unreliable. The limited bandwidth could be
better used by hosting prerecorded audio on a webserver served up by
RSS.

If live broadcasting is a must then tune the software to record mono
with a sample rate of 22kHz and encode the MP3 stream at 16kbit/s. CBC
radio uses similar settings for their low bandwidth radio stream. It
does not sound great, but it is not too terrible. With overhead you
should be able to serve 20 users. (a number of howtos recommend
doubling the mp3 bitrate when calculating bandwidth requirements.)
