^^^^^^^^ Not!!!
Their is no multiple keybaord support in XFree86 4.0, 3.3.X or in the
linux kernel. XF4.0 does support multiple video cards and so does fbcon to
a degree (It has problems).

2.5.X you will :-) I already have a experimental kernel running with
mutiple VTs.

Nope not with XFree86.

Since ggi uses both the /dev/event and /dev/fb interface then yes it is
very possible to support many users. Note this requires some big changes
to the X server.
