I think Bryan is asking if a BDB repository can be hotcopied to a network
drive.
I think this may well not work, since once the filesystem copy has been
made, Berkeley DB recovery is run on the copy.

The same endian-ness and same BDB version will suffice.
A simple "svnadmin recover" will rewrite the OS dependent bits for a new OS.
