Ad-hoc networking is even more powerful when combined with Internet Connection Sharing (ICS), a built-in feature of Windows that allows multiple computers to share a single Internet connection.

Additionally, ICS can allow you to share a VPN connection, and it can provide a way to connect a computer without a wireless card to a Wi-Fi network.
