Hi everybody,
I'm developing this multi-shop feature in PrestaShop 1.2.
Advantages:
All shop use the same 1 source code, 1 database, 1 addon domain (some parked domain ).
Share modules, themes, language but each shop's data and image directory are seperate.
Only need to upgrade once when PrestaShop releases a new version.

You can see some demos below:

I have difficuty when i must change path to tmp directory in Admin Tabs files in /admin/tabs directory manually.
If you have a solution for this problem, please email to me at developer[at]sieuhostvn.com.
Thanks.
