By the way, you can verify that things are exported somewhat as expected 
by checking with showmount -e
Also, rpcinfo -p is good, to check that both mountd and nfs is actually 
registered and running.

If you change /etc/exports, you need to kick mountd (send it a HUP) for 
it to actually read in the new exports file.
