Yes - that's a good example. Git is far more powerful
and a different paradigm for CVS. Someone had to think
outside the box and come up with a new way of looking
at things. I'm trying to do something like that with
this idea.

To me it make more sense to get rid of file
permissions and look at people permissions. It reminds
me of a story a friend of mine told about her 4 year
old son.

The story was that they were driving down the road
when they saw a wheel come off a truck. The son said,
"look mommy, that wheel lost it's truck."

To me files are like the wheel. Rather than having the
file know all it's owners it makes more sense for the
owners to know it's files.
