Is There an Easy Way to Export Subsite Store?

I'm just thinking about how to design my platform. I want to use MarketPress essentially as an online gallery for a particular industry. I would basically be hiding the e-commerce functionality from my sub-sites. If a customer wanted an e-commerce functionality, I would export their store and host them completely apart from my multi-site. The reason for doing this primarily for security concerns.

So my question is - Is There an Easy Way to Export Subsite Store?
