Obviously you need more computers (decoding system) for visually 
monitoring all your multicast streams. The CPU and memory requirements 
are dictated by the multicasts itself. If it are big streams, then it 
requires a lot of CPU.

Or you could use one visuall monitoring system that browses through all 
your streams every, eg: ~5 seconds.

Or write a heartbeat/health monitor for the streaming VLC's. One of the 
VideoLAN consultants/partners called M2X (www.m2x.nl) could do that for 
you, if you are interested.
