My problem is this sentence in the spec for seamless: "This will cause 
links to open in the parent browsing context."

In an application like 
http://test.rapid.ch/de/haendler-schweiz/iseki.html, the external page 
should be able to re-call itself inside the iframe, for example if a 
sort link is clicked or a search form submitted.
