Thank you so much, I will check this GIT bundle....
Since you asked, here are my answers suffixed by MHS >>

Do you also have remotes setup that provide backup and central authority to the projects..?

Is it networked? Internal control, external internet, sneakernet?

yep, you have lost the validation & verification capability of Git's sha1/oid and DAG.

Remotes, remotes...

I think the solution you need is `git bundle` https://git-scm.com/docs/git-bundle. This is designed for the case where you do not have the regular git transport infrastructure. Instead it records the expected data that would be 'on the wire', which is then read in at the far end. The bundle can contain excess data to ensure overlap between site transmissions.

You just run the projects in the same way but add the courier step for shipping the CD, or some password protected archive as per your security needs.

Everything is should be just fine (more or less) and somehow it will just work. ;-)

MHS>>> I am hopeful! Thanks a lot
