A lot of customers would like to be able to 'brand' the look and feel of how Exchange Labs is presented to end users with their own look and feel.  This can be done inside of the OWA Premium experience by using co-branding, you can add your own logos, color schemes, links and so on.  Read more about this here...I will blog on this topic eventually :)

Other colleges want to go a little further, and keep users of Exchange Labs completely within their portal environment, and the way that a lot of colleges are doing this is through the use of iFrames. I have included a sample of this technique below.

The HTML required to do this is simply:

<iframe style="width: 500px; height: 375px" src=http://exchangelabs.com frameborder="3" scrolling="yes"></iframe>

...of course you would not use the dimensions I have used!

Enjoy!
