Yes, a good idea.  I believe the AI will switch production automatically.

I think whoever suggested it should make a patch.  The only problem I see 
is a boat that zigzags between two cities that are building a boat.  
Possibly this can be solved by adding bool need_boat to choice struct.
Then a free boat will
(1) look for existing passangers
(2) look for virtual passengers in the city it's in
(3) look for virtual passengers elsewhere (indicated by the city building 
a boat).

I am planning to change the city building code so that it builds the unit 
first if there are free boats somewhere, but the above code can be 
incorporated there as well.
