I'm afraid I don't know too much about PS/2.  Take a look at
www.beyondlogic.org for more info.  It appears based on a
bit of info they have there that the data/clock lines are open
collector (on a keyboard), but your PIC (unless you work it as
such) will NOT have OC I/O.

Okay, a little more searching produced this:
http://panda.cs.ndsu.nodak.edu/~achapwes/PICmicro/PS2/ps2.htm
from my own alma mater, North Dakota State University.

There is a little on there about connecting a microcontroller and
KB concurrently.  I think, anyway, but I didn't read it too hard.

They suggest making your own OC drivers for the PIC.  May be
worth a read.
