Hello, Simon:

I'm the last you would want to give advice about this question, but even
though I am not a programmer, I have been using git to sync on three
different systems.  I am using a flash drive as a cache, so to speak.  I
followed some tips from the Emacs org-mode mailing list to get this going.
It wasn't simple for me to recover when some files got out of sync on one of
the machines, but it was simple enough that even I could figure it out.  I
used a bare repo on the flash drive and push from each machine to this, a
very simple procedure that can be automated through cron, and pull to each
machine also from the bare repository.  I am not syncing a programming
project, but my various work.

Again, I am the least clueful you will find on this list, but if you wish
for me to tell you the steps I followed, that is possible.  One of the
mailing list threads that got me up to speed relatively quickly was at this
link.  (Hope it's ok to link another mailing list from this one.)

I apologize if the existence of a bare repo as an intermediary is a problem.
This can be done on a server as well.

You can know the name of a bird in all the languages of the world,  but when
you're finished, you'll know absolutely nothing whatever about the bird...
So let's look at the bird and see what it's doing---that's what counts.
