But you have to maintain a mapping of which channel corresponds to
which device. Fine for techies but not much good for mass market
appeal. Ditto with using ARP.

No need for analogue switches. Just use transistors off the outputs
all commonned with a single oscillator -- since no two outputs will
ever be active simultaneously.
