Assuming the stream fits in memory and just has multiple people accessing it I suspect it could be clustered with Terracotta. Though I would need to know more details to know for sure as I'm not that familiar with how they work and are implemented. My thinking is that everyone in this case is essentially sharing the same stream so really only one instance ends up in each jvm and all the meta-data associated with each user is only in the jvm where the person is connected.
The live stream is pushed to the subscribers just like what Remote SharedObject does so if configured properly I believe it can be clustered by TC. But I doubt that this is practically realistic because (1) The amount of AV data is much bigger than that of RSO. So much more data will be transfered across the nodes. (2) When the amount of data arises, the transfer latency will also arise and the real time requirement of live streaming is compromised. Anyway we can implement it technically and whether it's practical will be decided by the application. Timon Reinhard wrote:
