the attaché's O.N.A.N.: InterLace's continental dissemination deals — "His duties here involve migrating with…"
His duties here involve migrating with the Prince and his retinue between InterLace’s two hubs of manufacture and dissemination in Phoenix, Arizona U.S.A. and Boston, Massachusetts U.S.A., respectively
Context
The O.N.A.N. entertainment apparatus shown as continental statecraft: a Saudi Minister of Home Entertainment crossing hemispheres to "cut another mammoth deal" with InterLace, whose "two hubs of manufacture and dissemination" run the Phoenix-Boston axis the whole book pivots on. The dissemination network is not just media but a geopolitical export good — the thing foreign legations fly in to buy — which is why the samizdat that runs on the same pipes will register later as a national-security event, not a piracy one. (The Entertainment's content and the attaché's spectation are entertainment-self's; taken here only as the deals/dissemination-as-geopolitics layer.)
