Windows Meeting Space is an application that comes with Windows Vista that allows you to facilitate ad-hoc meetings over Peer-to-Peer wireless networks.  This makes sharing slides, notes and handouts much easier as it's just a case of dropping a document into the shared area and everyone connected to your meeting receives the file.

Check out my screencast on Windows Meeting Space to see what it can do.

When you run Windows Meeting Space for the first time it configures the firewall to allow specific ports to be opened for the application to run.  If you are an IT Admin and want to open these up ready for your users to start using Windows Meeting Space then you configure their firewalls by group policy.  This means they won't be prompted by UAC to open up the ports on the firewall manually.  Here are the ports that are required for Windows Meeting Space:
