I was going to suggest AFS: http://www.openafs.org/ but right on the home page is states read-only replica copies - d'oh!
If all the file servers can work off the same drive (i.e. a volume on a SAN) you can use a clustered file system like Melio http://www.sanbolic.com/melioFS.htm or PolyServe. I think PolyServe supported file locking over the WAN but there were some obvious performance implications. Now that HP has bought them, I'm not sure if you can buy it as software only and if it has the same functionality - it's been too long since I originally looked at them and their web site is crap.
