I tried using the option --mirror but then the config end up in a way
that 
all remote repositories master branch maps to exactly the same name. 

However changing the config file manually I did get one that works more
or 
less as I intended. 

So with the below config I can create an empty directory and in that do 
"git --bare init"
copy in the config file and any objects I have laying around. 
then simply put a cron job that once a day do a
"git remote update"

the resulting repository is then possible to clone. And as long as no
repacking is done the object data will be shared. But to share data even
after a repack I guess I need to use GIT_ALTERNATE_OBJECT_DIRECTORIES
for my local clone. And then I need to be very careful when doing any
pruning on the download repository since my local clone could need data
that is no longer needed in the download repository. 

What would a safe procedure be ?? copy all data in the object hierarchy
from the download repository to my local clones then do a gc in them
starting from the download repository.
