That's what user accounts were made for. I wish that it were easier to make just one really powerful computer with a bunch of smaller workstations. Like a fuck-you huge powerful Xen hypervisor with a bunch of thin clients running virtualized sessions with shared storage that just do everything over the network. 21st century mainframe in the 1980s style.

I HATE moving files between computers. Rsync is great and all but I want my user to be my user, no matter what workstation I'm using.
