If he's running out of disk space as it is, he may have some difficulty
finding a place to migrate it to. And there's a potentially big performance
hit for using something like NFS instead of local disk. Given the low cost
of modern SATA nad high-speed IDE drives, there's little reason to use NFS
for something like thus unless you need some sort of weird
high-avaialability network appliance setup.
