FSFS on NFS in a load balanced setup

If for the purposes of load-balancing, I wanted to have several servers
share a set of Subversion repositories via a NFS mount, what issues might I
need to consider? Let's assume that I am using an up-to-date operating
system and the NFS version supports file locking (as in NFSv3; I assume that
is correct). Is it safe to say that Subversion would manage multiple
simultaneous writers to the same repository? In other words, the first
writer would get exclusive access to the repository and the others would
need to wait until their turn came around.

I've searched the archives and found quite a bit of anecdotal evidence, but
nothing that I would consider definitive on this point. It seems that one
possible solution is to use a clustering file system. Does anyone have any
suggestions (preferably something "free")?

Thanks
