TxTenna Is Live
I wrote about something called TxTenna back in May. It is a way to move Bitcoin from one wallet to another without needing to be connected to the Internet.
And here is a blog post by Richard Myers, the engineer at GoTenna (a USV portfolio company) who managed the TxTenna project in which he explains how it works and why they built it.
And for good measure, here are a few more links:

Certainly this is not a mainstream use case, but it does showcase the resiliency of decentralized systems and that is pretty neat.
