The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

Replace Caps Lock with Esc

Use setxkbmap to remap the key (does not require a daemon and is independant of your desktop environment or window manager). Don't forget to add the command before the exec gnome-session (or similar) line in your ~/.xinitrc or ~/.xsession.

setxkbmap -option caps:escape

setxkbmap can be found in extra/xorg-setxkbmap.
