  • Radio streaming? (transmitting from "...somewhere in the mesh"?)
    • A certain well-known VoIP app can't hack it on an XO. Considering that it's effectively the equivalent of audio streaming (albeit p2p), this might not be feasible. Then again, it's just was probably a half-***ed port of a known pile of slop... Acquired by closed-source company; VoIP on Linux is still a pipe dream, so radio streaming will be too.
  • SOS/Post-catastrophe app (how to fit a collaborative documentation effort into =<512MB? or make it decentralized?)
    • Someone's partially addressing it with ham radio ([1])...

    1. Each XO gathers info, establishes pt-2-pt comm links with nearest 2 neighbors (min. for msg. relay)
      • Is there a way to make long-distance multi-node pt-2-pt contact?
    2. As users enter information, suggestions could be given to the user (how much water x number of people need, how to recognize possible water-borne diseases, triage how-to)
    3. Once a relief center shows up (w/ hard drives), acts as XS/server...
      or a real one - it would make sense that schools would become impromptu first-aid and triage stations
      ...XOs spot it in the mesh (?) or by mesh-relay and U/L upon discovery (deltas thereafter)
      • But how long until relief shows up? How much data captured in that time? What data would be the most urgent?
    4. Comms are transient (vid/pic/voice), but written info (chat/DIY wiki) would need context awareness - geo/GPS, people/relations, needed items, status (Injured/killed/infirm)
      Might be better served by smart-phones? Might too gruesome for kids to do, but parents would probably rely on the kids to do the data entry... hmm... :-/
    • Caveat emptor: Batteries might drain before relief arrives, and there might not be any power source.

Didn't work ;-(

  • Build KDE 3 from scratch (because KDE4 is almost Java-like in resource hogging).
    • Takes a whole day on a 2,5GHz G5 Quad; it'll probably take a week on an XO :-(

  • Social network/cultural exchange/distance learning activity? o_O

    • HOW?
