It's funny you should mentin that - that is what is in place at a couple of locations, but we have been told by the power authority, that this is illegal, and must be removed.
I/we wanted to do exactly that to every amp location, but when we approached the sparkies to look into doing it, it hit red-tape, and is actually illegal to do, so we can't do it like that, and we have to DISCONNECT the ones that have the dual-supply now to be compliant with the law.
The issue is that it is illegal to use the power supply from one address, to power ANYTHING at another address. So while a dual 230v supply sounds ideal - and actually IS ideal - it is not legal, so we can't do that, unfortunately.
As I say - once the power company found out that we had done that historically about twenty years ago at a few locations, they demanded that those hookups be disconnected immediately.
So, we're stuck with UPS's at each amp location, or some other method of powering the amps at each location. I personally am rather liking Rob's idea of using a 48vAC central supply, and reusing the now mostly redundant grease-filled telephone cabling that pretty much runs everywhere, and definitely to every box with an amp on it, so getting a LV AC to every box from a central PSU via the phone cables would certainly be doable, but just weather we could get enough juice from that LV supply, to then power the amps is the question.
Lots of things to think about, anyway!
