Look, this is all fine and good - everyone with two brain cells to rub together immediately thought "mesh network" - not for Egypt, per se, but anytime in the last four years that this issue has come up.
But you go digging into the guts of this and you'll find that you only have to get about three levels deep before the whole thing is a mess.
Start reading the mailing list archives of MANET, BATMAN, OLSR, and so on, and you'll find that there are serious, serious math/network[1]/graphing/etc. issues that are nowhere near to being solved on any scale larger than your neighborhood.
Ok, if you map hyperlattice to a sphere surrounding Earth (for other gravity wells, use a hierarchical subnet) derived mostly from WGS84 position fixes, and otherwise visibility/ToF mutual triangulation and store only local deviations from idealicity, and implement long-distance via VPN over Internet initially, and use geographic routing where are the scale limits? I mean, sure, there are a gazillion ways to do it wrong, and only a couple to do it right. But this doesn't mean the problem is unsolvable.
So, a standalone wireless BBS ? Golden. The knee jerk "I (somewhat) grok the OSI model and some related bits of trivia and I think ya'll should just set up a mesh" ... not so much.
