Script to run an esound stream from soundflower to a pulseaudio server

streamit.rb

#!/usr/bin/env ruby

# Requirements: 
#   - A PulseAudio server running at the host in TO below.
#   - SoundFlower installed
#   - ESound installed (on mac, brew install esound)
# Select SoundFlower (2ch) as both Input AND Output devices, then run "streamit start"
# otherwise you don't have to worry about anything; it's a daemon, will run in the background, 
# once you're finished just kill esd or run "streamit stop"
