[tor-onions] ramdisk based onions sites

Would there a be a significant security/privacy advantage to running a .onion site in a VM that lives entirely on a ramdisk?

The downside obviously would be that anything not backed up would be lost in the case of a reboot.

To me the upside is that it would be very difficult to see anything that had been running in the VM if it needs to be dumped in the event of an emergency. I've heard of techniques that can get bits of data from ram that has been turned off, but I don't think that's easy/inexpensive to do.

What do you think, group?
