PC STORESI don't really know -how- arelith did it but they had player owned 'stores'
basically it would be something like the display case or weapon rack placeable
you paid rent on it to reserve it (like how you reserve rooms in the Governor's Hotel)
you could then drop in items to sell and select the price mark-up
sales went directly into your bank account
the Red Vardo and Clockwork both work really hard at this and i think those would be the first two deserving of such if something like this were implemented
although i could see one also added to the mist camp as a coveted spot
if you let the rent lapse the store would be available to the next person who paid rent, all inventory currently in there would be destroyed
PC TAVERNArelith also allowed players to lease the tavern. the rent was very expensive and usually more then you could usually make so it turned over relatively often
all food and drink sold - the money went to the owner
players also would tend bar and sell food and drink
City of Arabel also had an entire player-run village. it was very successful, everyone loved being a part of it. one dm worked hand in hand assigning tasks to players and helping 'build the place up' based on what players did (and also others attacking it or trying to destroy it politically)
it only ceased as a concept because the DM stopped playing but even years later everyone that knew of it/ was involved still speaks very highly of it.
When i look at the server i think of things like coffee house in port or the abandoned inn near midway as perfect places for such an experiment
it also works as a player magnet to draw people to one place which always help for getting other events organized or to start off from
just some ideas to push Soren and cuddlegutz over into insanity
