How to serve customized webpages?
We have a basic service that some people use but most people want their "own" as in custom solutions to their needs.  We are planning that now, so i wanted to have a great conversation with our community about it:

What would be the best way to serve custom pages designed for individual clients.  Like do a php redirect to their page via session authentication or hard write the same website but with their needs in mind?

So for example:  Everybody who wants the existing solution go to www.domain.com and sign in.  But those who want customizations as in features, analytical tools, can login to a subdomain created by us an then including the features they need.  

So its either we do PHP redirects and have everybody under that one system or if they required customizations, we physically create subdomains and serve those needs?

Thanks.
