There are several ways to do this. I prefer the following: use jQuery
[1] to change the behaviour of links:

     $('a[href^=http://]').live('click', function(evt) {
         $(evt.target).attr('target', 'foo');
     });

In English this means:
- for every 'a' node that has an attribute 'href' that starts with http://
- (even newly created ones)
- do the following:
- set the target of the link to the name of your (i)frame

(you would need to load jQuery before you can do this)

It would assume you have an (i)frame with the name 'framename' like this:

<iframe name="foo"></iframe>

But, this is just one option. Others might have better suggestions.
