I'm looking for a plugin that will keep track of how many times a block has been walked on, and after a configurable amount of times, the block will turn into a different block. My aim is to have 'people trails' automatically created as people play. I would like to have a config that would allow me to specify what blocks are affected by this, and what block they would turn into, and how many 'walk overs' would need to happen before the change occurred. For instance, I would set dirt and grass blocks to turn into brown wool after the block has been walked on 20 times. Jumping on a block would speed this process ( meaning a jump would count for 10 walks ) I don't run a separate SQL database server, so if this can't be accomplished with flat files I won't be able to use it.
Ooh also, if anyone creates this awesome idea, it could have WorldGuard capability so in defined places like spawn people can't make trails
