We cannot have SIFT or SURF in skimage because of patent constraints,
but we are certainly interested in STAR (consensus).  The binary
features would also be a very good contribution.

Could you describe what such a framework would look like and do?

I meant detection, and specifically referred to an alternative way of
implemented Viola-Jones that would avoid patent restrictions.
Alternative algorithms would also work, but I am not very familiar
with the literature.

All prospective candidates are more than welcome to share their
ideas/interests here, so that there is limited overlap.

I think I mentioned this in another mail, but it would encompass
efficient reading, writing, seeking, and real-time display.  Long,
long ago I wrote this for Octave:

http://octave.sourceforge.net/video/overview.html

I think we can definitely trump that by now in terms of functionality.
