I've searched some more on the internet, and it seems that what I want
to do is:

- add this on the remote configuration (so that local folders now all
  start with a '.')

nametrans = lambda folder: '.' + folder

- add this on the local configuration (to reverse this change)

nametrans = lambda folder: re.sub('^\.', '', folder)

Is this correct?

Now regarding the migration to the new scheme, can I just rename the
folders locally an do the nametrans change, or do I need to re-download
everything? In other words, how does offlineimap store the information
about what is synchronized, and will this information still be correct
after a renaming and nametrans change?

Thanks,

Alan
