I was thinking of setting up a few at various locations .
It will, but the block chain size is getting to be the problem with running it on a Pi (it takes a 64GB SD card to run it now or it did).
Sooner or later, it's going to take a 128 GB SD to run, or a USB HD on the Pi. And I don't know how much lag time USB HD would have on a node.
same.
I even tried storing the blockchain on a USB HDD and it still wouldn't stay running.
People out thetre have a way to turn one into just a transaction verifying node (no --generate command I believe);
But that doesnt solve my problem of needing a fallback if CK goes/shuts down =)
nicehash has a solo pool that runs almost the same code..

if you want a backup its something to consider.
