Not all organizations are ready for distributed version control

While evaluating git and mercurial for the company, I suddenly
realised that we still had developers struggling to comprehend svn and
generally the whole concept of revision control. They still work (in
secret I might add for if I catchem at it I'll cut their hands off) by
creating .old1 .old2 etc copies of files when they need to make
changes or try something experimental.

So, making the move from a centralized version control system like
svn to a distributed one when some of the team are living in the stone
age is going to cause a lot of trouble.

I have to weigh this up before I commit (no pun intended) to git/hg.
