Greetings to the Broadleaf community.

In my quest for a solid, Java based platform, I discovered Broadleaf and Shopizer. Both looked good, but I opted for the former (for now) based on good first impressions on support and documentation. But before proceeding with installation to evaluate, I have a couple of basic questions.
1) My web server will host several shopping sites (unique domains). Your front page states: "Multi-tenant, multi-site... a platform for your multi-everything needs." Am I correct in understanding this to mean that just the one Broadleaf server installation can serve multiple domains, with complete separation between administrators?
2) Some domains are built on Magnolia CMS. What is the typical approach when integrating Magnolia with Broadleaf? Embedding Broadleaf elements in Magnolia pages, or keeping a clean separation between Magnolia and Broadleaf pages?
Thank you in advance for any assistance on these matters.
Regards,
Chris.
