Mounting a remote (not on same network) hard drive to another mac
I'm trying to find out if it is possible to mount a remote computer/server's hard drive or share to another computer. I want to be able to exchange, create or modify the files. I know you can do a remote desktop but I'm not looking to share the screen just to mount the hard drive. I've researched many articles and keeps taking me back to various types of screen shares. Any help would be greatly appreciated.
iMac, Mac OS X (10.6.7)
