How do WebBIZcard smart vanity URLs work?

Each individual receives a set of vanity URLs with his or her name coupled with a preferred-domain name, for example Joe.AnyDomain.com/eCommerce, Joe.AnyDomain.com/services,... and Joe.AnyDomain.com/profiles.  These URLs' file suffix names are user-selectable, creating limited privacy controls, and have associated exchangeable XML data.

The XML data enable individuals from differing second-level domain names to exchange data at websites, thus allowing the creation of communities and markets.  Each URL also browser displays independently, creating a URL for communications uses  Third-level domain names can be created within the second-level's DNS settings or use WebBIZcard technology to create these rapidly.
