Widget support for a dynamic 'URL'

There is a website http://planefinder.net that displays the current location of aircraft in real time.

This web page is programmed to refresh in timed intervals and display the last real time location of each aircraft. [I hope that makes sense]. This way you can track an aircraft from its point of departure, the route it is following and the point of arrival.

Will the iBooks Author Widget for 'URL's constantly display the last refresh of that webpage as they occur whilst that page is open in the iBook? or is a better option simply to Hyperlink the website?

Help is always appreciated. Ant..
