I think you overlooked it... its empty...

vnc does no multicast (in the tcp/ip way)

For that purpose, you can connect more than one viewer to the same server, that 
will suit a need.

On top of that, to restrict/spread the bandwidth of the server machines, there 
is such a thing as a vnc-proxy or such but I don't have any experiece with that.

To limit the bandwidth, best to limit the screen resoultion to 800x600 and use 8 
bit colors (256 colors).
Then point more viewers to the same server.

If there is some performance drop, try to find the bottleneck. If that is in the 
network, use a higher compression. If the cpu is the load, drop compression and 
use raw network trafic.

If the vncserver is M$Windows based, twiggle with the polling settings.
