Is there an easy way to pull the subheader (.tn-utility-nav) bar into a clients none Tessi site?

It's been refreshingly easy to match up the look and feel of TNEW to our clients existing website.

Once we transition to Tessi, this website will be remaining as the brochure website. It will hand visitors over to TNEW for login, ticket purchasing, donations etc.

To take the consistency between the two sites one step further, is there an easy way to pull in the session specific HTML code for that block?

This way, if a visitor is logged in on TNEW and clicks back to the brochure site, they will still see that they are logged in, if they have something in their cart, it will show etc.

Thanks,

Dan
