using file:// requires NFS in this case since the data isn't local
(its on the netapp). svnserve uses a TCP/IP socket and negates any NFS
slowness. doesn't it make sense to *always* use svnserve when the data
isn't on a local disk? by removing NFS it should be faster then
file:// over the network, no?
