2 mice?

[Javasnob]

Is it possible to have 2 mice under X? Has anyone tried this out?

Absolutely. In fact, I think the last couple of distros I tried would allow multiple pointing devices by default.
The /etc/X11/xorg.conf might need an additional entry for each mouse beyond the first one, looking something like this:

Section "InputDevice"
  Identifier "USB Mouse"
  Driver "mouse"
  Option "SendCoreEvents"
  Option "Device" "/dev/input/mice"
  Option "Protocol" "ImPS/2"
  Option "ZAxisMapping" "4 5"
#  Option "Buttons" "5"
EndSection

This is what I use for a USB Logitech wheel mouse. Uncomment the last Option for a mouse with more than two buttons and a wheel, and set the number to however many buttons the mouse has. Also, check for the protocol that best matches your extra mouse.
