Now, are we talking exporting writeable to everyone, or _any_ NFS exported
writeable partition?

Let's say that I have two machines, server.foo.com and client.foo.com

server has one NFS exported volume which is for client.foo.com (diskless).  

showmount looks something like this:

 % showmount -e server.foo.com
 export list for server.foo.com:
 /export                            client.foo.com


is this exploitable?  How would it be exploited?  Is there a way to keep
people from exploiting it (besides not exporting it)?
