I saw similar projects before, but for Darkwire you need at least one node in the network needs to be connected to the internet.

Only realistic way for easily giving bitcoin to someone without internet is to use something like Satochip Satodime cards with pre-loaded Bitcoin.
This is physical card you are giving someone as a gift, just like you would give someone euro or dollar paper bills.
