web interface to rooms booked in Exchange?

If you have built a web interface to Microsoft Exchange to provide a
public "what's
going on today in my (building|organization|department)" would you contact
me?

We're moving our room booking from another system to Exchange, and the
part we don't have is something that lets visitors see what's going on in
different rooms during the day.

Thanks,
Tim
