I'm designing a simple framework for small websites to be used in an intranet. The websites will all be similar, but there will be a few pages, or controls on pages, that are different. I would like to be able to version and maintain the common framework part of the websites as if they were a regular library - if I need to update CSS then I only have to do it in one place. Can I package-up ASPX files, images and CSS and distribute them like this? What am I missing?

My goal is to allow the developers of the few core content pages to get up and running with the websites quickly, with standard styles and images.

Thanks!
