Guild of the Nine (Wonder) places a Mercenary Depot in all of the owner's cities, and enables all other players (regardless of their own tech level) to build the National Wonder Mercenary Depot. Then, the Guild owner can hire Mercs in any city, and other players can (after building the national wonder) hire Mercs in a single city.
Considerable perk for the guild owner, leaves the function available for all, and quite easily coded.
Is this actually going to happen or did Xienwolf punk me or something? I don't see it in the change log.
