      As to my code, I have several questions:

Yes, this surely is neccessary. A mover that is screwing up maps would be
terrible. Keep in mind that movers are often placed below the floor.

Like Mark said, exclude objects with the following "flags" from movement:
FLAG_IS_FLOOR, FLAG_NO_PICK, invisible

Also exclude everything with "weight 0". This should prevent
moving spell effects/ connected stuff (triggers,detectors,gates etc)
and the likes. I hope none of them uses weight for internal calculations
or other forms of mess..?

      In using these, how much do I have to worry about CPU time?  If no object

CPU time, say "performance", is an important issue. Try to make your
mover function as efficient as possible. E.g.: Loop through the items
on the mover's square only once. If possible, avoid checking every tick
- instead check only when an item was added. Exclude spell
effects (-> "weight 0") from all checks and loops at first.


In addition, I have a small feature request for the new movers:  =)
If movers have the connected value set, have them move objects only
by activation. This would allow some cool things. Like moving NPCs
"on command" for example: You speak a keyword to the guards - and
they step aside to let you pass.
