Sometimes a worker will ensure the job is well done in order to receive a better tip. For example - a wait staff may be more attentive knowing that they will receive an appropriate tip - however if they disregard their customers they accept that the tip will be little to non-existent.
I am currently doing the following:
Steamcast: - 24/7 relay of other stations. - Accepts a relay of live music (via NiceCast) - Free [running on a Linux VPS]
NiceCast: - Stream music live if I want to demo some tunes to my audience - Mac friendly - $50
