I think the key to your problem is the "mapping" option of dtml-with. If
your class/External method returns a dictionary, you can add it to the
namespace like so:

<dtml-with x mapping>
	<dtml-var foo>
</dtml-with>

You do not need to explicitly create a new InstanceDict yourself,
dtml-with takes care of that.
