Hmm... bad links go to an installation page?? Aaron, do you know
anything about this?

Definitely root.. most likely a changed kernel and wpa_supplicant.
Maybe even a changed Wifi firmware... or it might not work at all.

Unfortunately no... this is one of the mysteries of Android.

Yes. Might be both device/kernel/android-version dependent. We don't know.

P2P is "wifi direct"... which means its "group of node choose a leader
which opens an access point".
Its not useful for multihop communication.

No and yes.
Olsrd can run on any kind of interface... ethernet, wifi (adhoc. or
ap/station), anything that transports IP is good for olsrd.
Its just a matter of the supported layer-2 topology.
