Hi, You can install each airtime server in a virtual host on the same server + 1 shared install of icecast for all airtimes for instance. Have a look to http://en.wikipedia.org/wiki/OpenVZ, it works fine with Airtime. Fred
Don't know about what you intend to do... I can just deal about what I have tested and know it works well for a long time...
Having a couple of virtual hosts will make your setup more reliable, especially a distinctive icecast instance. It's the only IP that is visible to attack for your listeners. Airtime instances don't need much ressources, just disk space depending on your playlists. You have total control on these hosts. On the other hand, icecast server ressources depends on how many listeners are connected. You don't have control on this.
Hello! Why on earth are you attempting to stack several Airtime instances on the same server, friend? Hopefully you don't intend to resell! Please, as others have suggested -- go virtual. Or better yet, check yo self! :-j
Icecast is by essence designed to support an unlimited number of streams. Limits depend on how many listeners are connected, codecs loads, and bandwidth you can afford for your server. CPU and RAM are not really a concern except if you expect 1000s of listeners at peak time.
Within one instance of Airtime, you can settle up to three streams using different codecs but the same radio program, which make 3 streams relayed by the same icecast server. On Icecast's point of view, they are 3 different streams and they can be issued by the same source or separate servers. This doesn't matter as long as each source provides correct credentials to be connected and relayed.
