I know the OS comes bundled with the XeroBank line of software (i.e., xb Browser, xB VPN, etc.). However, the numerous ads on the website and offered subscriptions leave me beffudled: does running this OS require me to shell out money in order to operate all the features? For instance, would p2p software work in an encrypted, anonymous manner? Is the XeroBank network freely accessible, or is Tor offered for the stringy? (I am.) And, there is a link to the source code on the page for xB Machine, but the hyperlink is broken. (The same applies to xB Browser, actually.) Thanks.
