Natural allies, it's weird that they're not already grafted together somehow.

IMHO, the ultimate feature-set would be:

* IIAB content library support, especially the new map features which rock

* wrolpi-like tagging and automatic updating when connected to the internet

* Othernet updating of content when satellite signal is available

* Toosheh extractor for unpacking files saved in an mpeg-ts on a USB stick

* Local Fdroid app repo

* Piratebox-like file drop area

* BBS or local forum message-board

* Mesh with other nodes, perhaps using NNCP or Scuttlebutt protocols to exchange messages over spotty connectivity or traveling relay nodes

If I had any software clue whatsoever, I'd be actively trying to graft all these things together.
