For all my permanently connected machines I use NIS for users and NFS for /home

Simply doing that will propgate any user settings to any
perma-connected machine that reads the same /home (assuming the same
software is used, ex. if gnome 2.8 is used on one machine it will have
issues with some of the things gnome 2.10 does with configurations)

For my laptop I maintain local users, which is just me, and I use
rsync in various methods to keep my files up to date.  I treat my
folders as if they were the equivalent to windows' offline, only no
automagic syncronizing, because I don't want my entire /home on the
laptop to be /home on the server (diskspace restrictions, other users
that don't use the laptop, etc.)
