A close runner up (believe it or not) is finding good broadband
I totally believe it. My ex-wife and I did a few years of nomading (just in North America and the Caribbean) in the first half of this decade, and finding internet connectivity was absolutely the most difficult thing about it. I imagine it's actually considerably easier, now.
what about options like the verizon global broadband satellite service? or similar things? are there any globally-available reasonably-priced global mobile broadband solutoins? tethering? etc.?
I've briefly looked up mobile satellite internet, and the cost is extremely restrictive: starting at like $600/month for a few hundred megs of transfer. This was for the ultra-portable satellite setups (the kinda thing you can throw in a backpack or a laptop case).
Any satellite service is pretty poor when the thing you really need connectivity for is SSH. These days, I could get away with a 3G tether in those situations, but cellphone internet wasn't like that then.
