Larry, would it be even remotely feasible to add a feature to bk that
checks out just the current state of the tree with no revision
history?  Or do repositories have to be identical up to the branching
point of the last mutual push/pull?  Maybe it could be done by
creating a special kind of repository that can only pull things from
the parent?

I'm thinking something along the lines of the client having no SCCS
files, sort of like doing a bk export from the server repository to
the client's machine.  Unlike export there would also be tag
information for future reference when the server needs to figure out
what's new for the client.  You could call the client side command
"bk rsync".  :)

I'm way out of my depth here so I have no idea if this is possible or
how much work it would entail.
