Hi
After reading the requirement, I think that the core requirment of the project is to support to set up the multi-stores more easier than Magento provided itself.
And now I have two questions about the subsite. Can you explain it?
1) about the subsites' domain, they are sub domains or standalone domains?
For example, now our main site domain is [login to view URL], and what is the sub site's domain ? [login to view URL] or other standalone domain, such as [login to view URL]
2) How to manage the products?
Based on your requirement, I think that you want to manage all products under the main site. And all other sub site stores can sell all products of the main site with the same price.
Is it right ? Or you have your own idea.
Please tell me, and look forward to your reply, thanks a lot.
