The current 4 port USB multicaster does work very well for keeping a mouse in sync. Having a wider version would have been nice. The only small caveat of it is that it seems to "packetize" the mouse input. The USB mouse connected directly is perfectly smooth. The USB multicast mouse replicates the movement in bursts that feels slightly jerky.

As for the switch caster that is a fabulous idea. Something that has two inputs one "keyboard" to switch and another "keyboard" to multicast. As long as they both work at the same time that would be killer piece of hardware. If it switched/multicasted both keyboard and ps2 mice that would be even better (4 inputs keyboard and mouse to switch and keybard and mouse to multicast).

Despite having separate boxes to do that already I would buy it for the cable/clutter reduction alone (it would have to be 5 outputs minimum to be useful with more being better)
