Question : How do I link an External Exchange Server to an Internal Exchange server to share calendar info

Hello all.  I have an odd issue that I need help on.  I work at a company based in the United States and we have a branch that is located in the UK.  The US branch has an Exchange server 2007 and the UK branch has an Exchange server 2003.  Both locations have different domain names (US - My_Company_Name.Org; UK - My_Company_Name.Org.UK).  The UK office wants to link or synchronize the two exchange servers so they are able to see the Free/Busy times from our calendars.  First off is this possible?  I don't know if the UK office wants to be able to see only a few peoples calendars or if they want to be able to look at everybody's calendar.  Second, if it is possible, how do I go about doing it?  Can you share calendars between different domains?
