I particularly enjoyed watching the clock on the stove. Lady 1 says something while the clock says 3:41 beside her. While she is still talking, the video cuts to a reaction shot of lady #2 where the clock says 4:07. There were many breaks in time like this that the clock gives away. I'm not a video professional but that sure seems like something any qualified director would notice while shooting.
Check out CouchDB. It is built around the concepts of distributed (and even offline) databases and handles conflict resolution. It employs optimistic locking.
I also couldn't run Parallels more than 15 minutes on my Mac Pro without it causing a kernel panic. I'm glad to hear someone else had the same problem.
I switched to VMWare Fusion and haven't looked back.
