My suggestions:
- Give stalls a permission system, similar to claims.
 - Give the option to have village owned stalls, with permissions that can be managed in the village menu. (perhaps have stall cost deducted from village upkeep?)
 - Let characters inherit stalls.
 - Let characters give away stalls.
 - Make stalls buildable outside of Boston
 
Please correct me if any of these options are already available.
