Yes, indeed.  But this will create a bundle with *all* the commits in a
tree, including ones which have possibly been pushed out already to the
development team in India.

In newer versions of Mercurial, you can also do this without the extra
'empty' workspace, by using the --all option of `hg bundle':

    % cd /ws/foo-project/releases/1.0-patches
    % hg bundle --all /var/tmp/wiredata.bundle

The initial `hg clone' of a repository may take a while, depending on
the link speed.  Subsequent `pull' operations are blazingly fast though.
I am pulling changes from the OpenSolaris source tree every week or so.
The current OpenSolaris source repository contains a little over 6,000
changesets for more than 40,000 files.  A `pull' completes on my home
DSL link in a few seconds (i.e. less than half a minute).

Creating a *full* clone over SSH to hg.opensolaris.org may take a while
though.

One of the easy ways to create *many* local clones in India is to create
a hierarchy of `workspaces'.  One can install a local `gate' in India,
and use the gate only for pulling changes from the official tree.  The
local India developers can clone the local gate instead of the remote
`master' tree.
