My name is Bryon Stout. I run a internet radio station (www.deephouselounge.com). We currently use Centovacast v3 for our auto dj software. I have it installed on my dedicated machine and can launch an unlimited amount of stations under the main instance. That feature is important because I have multiple stations that are all part of a network that I am building. Its also important for people who want to be able to sell shoutcast/icecast packages. I should also mention that centovacast can be linked up to whmcs for auto deployment.
Hi Bryon, Airtime is based around a calendar, so you would need multiple calendars to do that. For now, the easiest way to achieve this is to put a separate instance of Airtime into each of a number of virtualization containers. It's more complicated, but you gain some isolation between station instances.
