We're going to have a "buddy picture" (which in XMPP is an "avatar") for
each person that will be taken by the camera on first boot. It will be
changeable. It'll be available from roll-overs on each XO icon wherever
you see that icon in Sugar.

Yes, face recognition was heavily optimized by evolution long before
the emergence of humans. They say that you can tell you're getting old
when everybody you meet looks like someone you already know, which
fits nicely with the evolutionary model.
There is a study that says that all faces can be composed from 77
eigenfaces, which would allow very good compression.
