I think the most difficult thing is simultaneous delivery
of all objects, even if you can find the barter sets.
Also, people may want to personally check the value
of each found transaction. If people refuse 50% of
suggestions after they look at them (you can never perfectly
describe them in a formal way; people want to look at pictures,
free-form descriptions, talk to the vendor, etc.) and 10%
of transactions break (not delivered, etc.) then there is
very little chance to organize exchanges more complex than
loops of 3 objects.
