>From my experiences, the tar "filesystem" is the best one to
do this. You can transfer the tar archives (and add compression
if needed) between different operating systems using FTP or
any "Internet means" as well as via optical media, even the
use of floppy disks (if you still know them) is possible.

On one end:

	% tar cvf bla.tar <your stuff here>

On the other end:

	% tar xvf bla.tar

FreeBSD and OpenBSD use FFS / UFS file systems. Have you already
tried mounting FreeBSD partitions with OpenBSD or vice versa?

Of course, it's possible to transfer data via FTP, rsync or
scp between machines.

But because you asked about file systems, just try the mount
advice.
