Oh I see misunderstanding then. So what you propose is
basically a chown of the directory in question?

I tried the following 

Laptop1 to disk: disk is mounted with uid=1000
 rysnc -auvzx /home/oub/dir /media/disk/oub (id=1000)

from disk to Laptop2 disk is mounted with uid=1000 but user
is uid 1002

 rsync -auvzv /media/disk/oub/dir oub at localhost:/home/oub (id=1002)

Files get copied without problems, having now id=1002 and
username oub.

Edit hte files and Work... work 

try to copy back to the disk 

 rsync -auvzv /home/oub/dir oub at localhost:/media/disk/oub

Now it fails, even as 
sudo rsync -auvzv /home/oub/dir oub at localhost:/media/disk/oub

So it seems the only possibility is to have the same uid on
both machines.

Ps I had to add 

 sshd: localhost : allow

Otherwise ssh does not work.
