I had presumed that there's no state where Bubba is either holding or not
holding the rope. He ties the rope to the rock and when he pulls the rope
the rock moves. No one actually comes in and sees Bubba pulling on the
rope. I only chose to mention dex because the way I'm going with this,
each modifier has to know about what attributes the action checks so that
it knows if it is supposed to do its modifying.

That adds a twist and brings up an interesting point: how to deal
with actions performed by more than one person at a time, where the
efforts of each person involved should be considered in tandem toward
For me, there's no concept of two people pulling on the rope at the
same time and I'm not sure how I could handle it yet. The same sort
of thing applies to the "dig panama canal" command: how to have 20
people all digging the Panama Canal at the same time, and work
therefore proceeding much more quickly than if only Bubba were
Bubba is here digging the Panama Canal.

Sorry, digging the Panama Canal is a one-man job.
I wouldn't want to see that. Nor would I want to see two Panama Canals
being created side by side because Bubba and Boffo both decided to start
digging in the same room.
Perhaps the grouping system could be used. If you are in the same group
and in the same place as Bubba and you've typed "help bubba" or somesuch,
your stats are merged with Bubba's whenever the digging action is
performed. I seriously doubt this would work in all cases and could lead
to an occasionally unwanted situation where Bubba doesn't have say, the
intelligence to learn a spell, but if Boffo decides to "help bubba" as
Bubba's learning the spell, suddenly he could catch on. That example was
rather weak, but it illustrates the possibility of situations where you
wouldn't want helping someone to benefit that person in such a blatant
fashion. How to distinguish the situations?
Anyone else already doing something like this?
