Some big changes are coming not only to how the web functions but also to how it will feel for users. Basic web 2.0 operations - such as HTTPRequest - are set to be enabled with cross-domain access controls. This addresses some of the major issues of website interoperability, but also means that fun easy-going cross-site content-mashing is going to be replaced with one where you the external site must specifically grant permission. So simply linking to external resources to embed them - like this, say, or this - may become impossible.
