Different domains, single shop, overlapping products


HI Folks,

I am looking at the ReactionCommerce. pretty nice.

My requirement is to have a multiple domains with a single shop (domain can be
obtained through location.hostname on client for example).
Each domain may differ products or not (by a mongo selector for example).
Each domain may differ theme or not.
The accounts are shared between domains.
Different home and sitemaps for each domain including their specific products.

It is possible? Can anyone help point me in the right direction?

Thank you so much!
