Actually I understand current LP's do a mix of a global parser (drink
is avilable everywhere), and verbs bound to unique objects, but that's
another matter.

I'm a big fan of having verbs bound directly to their target objects. 
It works, its simple, its efficient, and it allows useful pre-parsing
by template ala ColdX.  The disadvantage as you write is the lack of
global defaults for common verbs like "drink".  

Happily this can be fixed with a touch of LP's parser layer concepts. 
Have the same verbs-on-objects that MOO, ColdX, and old LP's use, use
ColdX's template concept (a grown up version of MOO's), and then given
such template value weightings.  In my case I assign a weighting to
templates from 0 - 255.  Matching verbs/templates are searched for in
the normal manner (player, inventory, room etc), with the first
matching template which weight is over 128 accepted.  If no matching
templates are found with weights over 128, then the heaviest template
(largest weight) closest (least removed ala player/inventory/room) to
the player is taken instead.

This allows a drink verb to be directly and usefully bound to the cup
while still allowing a semi-intelligent default "Huh?" drink verb to
be bound to the player, master object, or similar for a global sense.

And thus you get state flags and all the endless horrors and nastiness
that they bring.  No thanks.

I don't attempt to resolve time much at all as far as player events
are concerned.  I don't do things like enforcing the speed of walking
etc.  If the player can etner twenty "north" commands in 2 seconds,
and get the server to compleat those commands as well, well, it will
work.  The exceptions are certain commands whose compleation is
inherently timed.  How long "Dig panama canal" takes etc.  These
things are measured diurectly in MUD time.

I also allow player commands to not be required to be executed in
sequence.  Thus the player can do:

  > run to house
  You begin running to the house.
  > shut door               // Command will be executed after "run"
  Okay.
  > !shoot at bad guys      // Command will be executed asynchronously
  You shoot at the bad huys.
  You have reached the house.
  You shut the door.
