I don't really `get' the distinction you are trying to make about
`mirrors' vs. `clients'. In the world of Mercurial there is no `client'
concept. Anyone who can `clone' a tree is a self-sufficient, fully
independent `mirror' of the original tree.

Mirrors are usually one-way in the FreeBSD world. They can `read' but
they cannot (and don't really need to) `write' to the main CVS tree.
This means that we are trying to solve the wrong problem, if we spend
too much time worrying about `read-write mirrors'.
