I'm putting this out as a suggestion because I only am able to play sporadically.
A group of players who spend a significant amount of time in-world, particularly spanning time zones, could get together and put together an expedited delivery service. They could establish a home base and share keys, then offer a broad range of items and a slight premium to auctions. The value-add would be fast delivery to your home street. Do you need seeds, or honey, or tomatoes, or a potion, and want it now? IM the dispatcher and a delivery representative would be dispatched to your home street within a minute or two.
I hope some people run with this. I hate having to wait for the frog.
