Yes we do. Even in the mimimun default multipipe configuration for Onyx2, as
soon as you have more of one pipe we do support as many keyboards/mice as
pipes, with an upper limit of two keyboards/mice per CPU module (CPU card
cage).

You are required to change a couple of Xserver config files and create a couple
of devices, but it is a step by step procedure.

We do have customers with up to 8 keyboard/mice with 8 pipes and four CPU
modules.

I am very surprised, in any case please ask for the reasons.
If you have an Onyx2 with two pipes, you MUST be able to do it.

For two pipes on Onyx2 you do not need ANY additional hardware, besides the
extra monitor, keyboard and mouse.
