10.04 64bit, NFS Server, NFS Client - no samba and not wanted

I am using NFS to share across my network. One thing I can't solve is this, for example:
I share my /home folder.
This folder contains links to places outside /home, specifically drives mounted in /mnt.

How can I share /home but specify folders I do not want shared within /home? (I don't want to do it by sharing /home/photos, /home/media etc)

Many thanks,
