How do I access a Global Address List from another forest?

Hi all,

I have a need for a Global Address List from one Active Directory Forest to show up either in or adjacent to a Global Address List in another forest's Microsoft Outlook.

We have two forests, well call them Forest A and Forest B.  Both are on the same university campus and no ports are blocked between them.  We do not have any types of trusts set up.  Both forests run an Exchange 2003 environment.  A user in Forest A not only needs to see their GAL, but all be able to access the GAL in Forest B.

Ideally, this needs to be something that is automatic; that is, it doesnt needed to be added manually (like an LDAP directory lookup) to each client machine in Forest A.

Id even settle for some export/import logic where the GAL from Forest B is imported into Forest A at some regular interval.

What are some of my options to make this happen?

He asked for some of his options and simple sync is another option, I've never used IIFP so I can't compare the two.
Thanks
