Lyndel wow that is commitment to perfection. I would never dream of controlling one device with 3 control protocols.

I use the protocol that givest the greatest flexibility and is more fault-proof. I like rs-232 the because it's initialized really quick and provides 2 way comm. Ir is only a single way comm ( so half useful sometimes), IP is ... i don't know ... I use it but ... a lot of devices thake an awfully long time to initialize it upon getting power (i tend to shut down racks when they are not needed) - some take 40 and more seconds, and there is always the switch in the middle. But true, it supports a lot of devices usually more than a home needs.
