You may be interested to note that NNCP integrated Yggdrasil support recently (though you can also run Yggdrasil at the OS level). Yggdrasil is an always-encrypted IPv6-based mesh, and is a perfect fit for something like ad-hoc wifi (since the nodes can discover a route to each other based even on RF paths).
Yggdrasil can also run as an overlay network atop standard Internet (IPv4 or IPv6), or both. It will opportunistically find peers on a local broadcast domain and find routes to other networks over the standard Internet if need be.
Feel free to drop me a note if you like; I had a very similar experience with SSB. NNCP, while it has a bit of a learning curve, Just Works. It processes thousands of packets for me every day (hourly ZFS snapshot backups for every filesystem I have), some of which are huge, and it Just Works.
