Remote Login without server

ok, this post is very basic and I might not be in the right area, but I would at the very least appreciate a point in the right direction... I have two iMacs running 10.3.4. i would like to store all of our users' profiles (all the preferences, bookmarks, etc.) on one of the iMacs. Then if someone wants to log in from the second computer, then would have access to their profile from the first computer. Is there anyway to do this? ps I don't own OS X server.
