Help wanted! How easy would it be to add MP capability to the swingdoor cog (the cog in the tutorial)?

Here for convienience

# Jedi Knight Cog Script
#
# h0_swingdoors2.cog
#
# By Heinz Högel 5/98 for free use in add-on levels
#
# This script controls one or two winged rotating doors. To start open/close
# action, activate one out of two possibly linked switches or send a user0
# message to this cog.
#
# Parameters:
#
# Door0
# Door1 - IDs of door things (one is optional).
#
# Switch0
# Switch1 - Surfaces with switches on. These switches can activate opening
# and closing of the door wings. They are both displayed as activated
# as long as the doors are moving and then return to deactivated state.
# Both are optional (without them you have to send a user0 message to this
# cog to open/close the doors).
#
# Time - How long a complete door swing should last (in seconds). Should be positive
# on startup.
#
# AutoCloseDelay - If greater than 0.0, delay in seconds for automatic re-closing of doors.

if (Switch1 >= 0)
SetWallCel(Switch1, 0); // Display first switch as deactivated

return;

end


If this is too hard would it be easy to add a switch control to Jeff Waters Drazen swinging door cog? (currently you activate the door itself rather than a switch). Without it I'll have to decide whether to simply have sliding doors or doors that are permanently open.
