From http://www.rocketboard.com/legal/priv acy.html:

When you install your RocketBoard driver software, you will be assigned a unique global user identification number (GUID). This number along with your IP address is used to help dentify you and your browsing habits and to gather broad demographic information.

Since they are using a GUID, they will know exactly who you are and everything you look at in their network. No doubt they will be providing your name, address, phone number, etc to any of their advertisers whose pages you visit.
