Managing store fronts on multiple domains through one CMS?
 

I am tired of Magento.

I have a number keyword domains for specific products I sell through a single online store.

What is the best way to manage these products through 1 cms/shopping cart system and publish those products out to the appropriate domains?

Wordpress has a Magento plugin to display products on blogs. Is there any better way that's simple and easy to configure/maintain? Just editing templates in Magento is a fucking nightmare... i'm over it. Too much for ~100 simple products.

What is the best way to do this?

Not that I've attempted this on a grand scale...

All sponsor info goes into a single MySql database. From there you can extract your niche specific data into xml readers embedded in your keyword domains, or even subdomains on your main site. (If you use subdomains, you will redirect your keyword domains to those)

Sounds simple in concept, a little more difficult to execute. Don't ask me to do it, a friend built it. He's already said he's too busy to take new projects.
