Is there a reason we would need to coordinate on what to exchange rather than, say, beginning with encyclopedias and textbooks then moving to a constant stream of notable papers, news, discoveries, etc? What kind of bandwidth can you hit with a cooperating neighbour where improvements become civilisationally important? How many bytes (megabytes? Terabytes?) of meaningful new data does humanity produce per second? I suspect it's reasonably low.
