Trying to coordinate trades when you play weird hours, weird days, or have unpredictable absences sucks.
The idea: a Nenyuk or site-appropriate trader NPC that facilitates trades between players.
The way it would work: you can offer a single item or a single container containing a single item type, at a certain price to the NPC. The NPC gives you a ticket. Players can then buy that container, with the items inside it, for the price you set. When you return to the NPC and "offer ticket," if another player has bought your container of items, you get the money, minus say...a 10% transaction fee.

You are carrying:
a small bag
> key . small.bag
In a small bag:
1.sapphire - a bit of unworked blue sapphire
2.sapphire - a bit of unworked blue sapphire
3.sapphire - a bit of unworked blue sapphire
4.sapphire - a bit of unworked blue sapphire
5.sapphire - a bit of unworked blue sapphire
6.sapphire - a bit of unworked blue sapphire
7.sapphire - a bit of unworked blue sapphire
8.sapphire - a bit of unworked blue sapphire
9.sapphire - a bit of unworked blue sapphire
10.sapphire - a bit of unworked blue sapphire
> offer small.bag 500
After making a few quick chalk marks on a wooden board, the corpulent, peg-legged woman hands you an etched stone token.
The corpulent, peg-legged woman says to you, in sirihish:
"That'll be 50 obsidian coins for the trade. Come back later for your 450 coins...if anyone takes your offer."
> list corpulent
the corpulent, peg-legged woman has the following goods to trade:
01) a small bag containing 10 bits of unworked blue sapphire for 500 coins
To prevent ridiculous offers from spamming up the agent, there would be a clearance mechanic built-in. E.g. after a certain time period, the item would disappear from the agent's inventory, and when you return to offer the token, they give you the item or container back and charge you the trade fee.
Sample Interaction
> list corpulent
The corpulent, peg-legged woman has nothing to trade.
> offer etched.token corpulent
The corpulent, peg-legged woman says to you, in sirihish:
"Nobody wanted your junk at that price. It'll be 50 coins if you want it back."
> get coins pack
You get a pile of allanaki coins from a bone-studded backpack.
> offer etched.token corpulent
The corpulent, peg-legged woman takes an etched stone token and hands you a small bag.
Alternatively, the NPC could simply charge you 10% up-front, and you could offer the token whenever you wanted to get the items back.
The code should do the ordinary checks for illegal items. E.g. no bags full of jade-emblazoned shortswords or pinches of spice in Allanak. No haggling mechanics involved. Maybe the agent in Allanak would require you to be wearing a merchant's token to offer new goods. Probably should be some weight-limit involved to prevent half-giants from offering up trunks full of rocks. Etc. etc.
Also, I mean...even though corpses are containers...and it would be an interesting way to confirm bounty pickups...probably shouldn't be able to offer corpses or a bag with a head in it.
