Related to iframes what I would like is something like <icontent> where you could do something like this:
<p>You currently have
<icontent src="http://me.com/basket_count.pl" />
items in your basket.

As i understand it this is tricky in iframes as you need to set the height etc which are prone to change.
This would allow you to create, for example, static product pages on a web-shop and only hit the cgi for the dynamic content such as the number of items in a basket.
