Think I saw the erlier 'easy' round, but clicked through to http://en.wikipedia.org/wiki/Vector_clock http://en.wikipedia.org/wiki/Vector_clock (kept updated with these posts, I noticed). Two thoughts: first, what about an application/example to DVCS problems ? Such as "Dave saw both Ben's and Cathy's derivations of Alice's drawing, but prefers Ben's with a small modification ..." Second, when is the xkcd comic coming out ?
