i think he's asking how to create another share so when he logs in remotely it asks him what he want to mount and gives him a choice of his home directory, the hard drive (if he is a privileged user), and the share
i know how to do this with netatalk in linux but i'm not sure if the same rules apply (it was just a creation and edit of a config file)
if this wasn't what you were asking i'm sorry but i'd like to personally know how to do this in 10
It's easier to do on OS X Server, but possible on OS X client. Here's how:
1) Create a new user called "Share" or something like it, do not give them administrator access. Setup the password, etc.
2) Make sure File sharing is turned on.
You will be able to share everything in their Public/Drop Box directory.
