Regarding the os running from ram, that's how Voyage works - everything is in ram. If you edit (say) /etc/fstab what you are actually editing is the copy of that file in ram. The changes get automatically synched back to the ssd on shutdown.
Certainly the last time I looked VoyageMPD Linux mounts read-only, which is not quite the same thing as "the whole OS loads into memory". Have you for instance run IOTOP to monitor disk access after booting? I'm not picking holes here, I'm just genuinely curious.
