Given a couple of `ifs' here... If the labels were compatible between
NetBSD/OpenBSD, and if Bob's VAX kernel were compiled with the FFS_EI
option, it should be possible for hime to mount the Sparc created
filesystem on his VAX.

From NetBSD 1.5 man page -- option(4)

     options FFS_EI
     Enable ``Endian-Independent'' FFS support.  This allows a system to
     mount an FFS filesystem created for another architecture, at a small
     performance cost for all FFS filesytems.  See also newfs(8), fsck_ffs(8),
     dumpfs(8) for filesystem byte order status and manipulation.

Or maybe he could dump the filesystem to a file or tape on the OpenBSD
systems and restore it on the NetBSD system?
