Inmarsat satellite access will get you internet from pretty much anywhere on the planet with upward line of sight, but it's pretty slow and very expensive. You should have caching components for all portions of your network stack, to minimize the cost of it (unless that really isn't an issue) -- cache DNS lookups, web requests, everything. Local wi-fi is probably enough for 30ish people, though you can probably spare the room for switches + cables, you probably don't have to. Setting up some local version control would probably be beneficial to, though picking which one is possibly political. Aside from that, the only other high-bandwidth thing that I can think of to mirror locally (that you haven't already mentioned) would be an apt repository, but that's probably overboard. Of course, I don't know the audience.
