[Icecast] Running Icecast2 behind Amazon Elastic Load Balancer (ELB)

We need a load balancer to allow for a single URL "entry point" to multiple
Icecast servers - we intend to host multiple Icecast servers behind the
load balancer so that we can expand / contract capacity as required - we
would add servers into the load balancer pool. This also allows us to scale
beyond the number of listeners a single Icecast server can support, while
still maintaining the "illusion" of a single streaming server.
It also provides redundancy / failover capability by allowing us to balance
connections across Icecast servers in multiple AWS availability zones.
I'm aware of some "playlist based" loadbalancing techniques using .m3u or
HTTP redirects to the icecast servers, but this is not ideal for us, as a)
we need to support some legacy players (eg. set top boxes) that don't
support redirects or m3u's, and b) using ELB allows us to very easily
provision backend health checks, multi availability zone redundancy, and
auto scaling of Icecast servers.
Hope that answers your question,
