This will work.

I really don't think that you want to run NFS over the wide area.
Not only do you have to be very very careful security-wise (i.e. do
it over IPSec or something and make sure your NFS is not visible from
the Internet itself) but do you really want to deal with the local
VM server wedging when something funny happens on the network between
the remote and central sites? It's not impossible but IMO you're asking
for trouble doing it like this.
