Hmmm, just a quote from the subversion-book:
"""
Other options can be listed with svnadmin help. As opposed to CVS, 
subversion is not based on RCS, but rather on the Berkeley Database. 
Make sure not to install a repository on remote file systems, like NFS, 
AFS, or Windows SMB. The database requires POSIX locking mechanisms, 
which these file systems do not support.
"""

Also, see the threads about byte-range locking earlier in this list.
Boiled down, I wouldn't do that.
