Hi Katy,
I have reviewed the support matrix for the product, however I'm not really familiar with the product and was a little uncertain as there had been a previous attempt to install the product which had not gone well and had caused several outages.
Typically only the global zone of the Logical Domain has a shared IP, with all hosted zones being an exclusive IP - the verbal feed back was that installing the product in the global zone prevented access to any of the hosted zones within that global - so just checking was all.
Unfortunately the person doing the work is no longer available, so the information I have is second hand.
Regards
Dave
