Is there a way (eg a plugin) to have the squeezebox automatically choose between running slimservers?

I.e. I want to run and use a slimserver instance on an actual PC should that be on, but also another slimserver on a NAS for when the PC isn't on. The squeezebox would poll say every 30 seconds while idle and you would be able to rank the slimservers in order of preference. Would give the best of both worlds - very repsonsive slimserver on a PC if that happens to be on, but still access to slimserver even if it isn't. They would both actually look at the same music library stored on the NAS.

Is there any way to achieve this currently? Would it be useful to others?

Cheers
