rendereing an IFRAME using Interwoven's portal ser

System

Hi.

I am new to portal technologies. My company is looking to push content out to our customers that use different portal vendors which include Interwoven.
I'm trying to find out if I can pull up an IFRAME(eg: cnn.com) in a portlet/gadget using Interwoven's portal server.

I have been successful in doing this with Sharepoint and Plumtree(v 5.0.2).
I am assuming that TeamSite is Interwoven's portal server product and hence I have posted this question to this forum.

Please excuse my ignorance about key concepts and terminology about portal development.
Any help or direction will be greatly appreciated.
