@Home is darn scared right now, and rightly so. They're losing everything and insiste on running from the answers, and instead embrace their failures. @Home techs are now FORBIDDEM from posting any negative, derogatory, or in fact any work related information on any non-offical @Home site. The memo in question mentions legal actions against anyone not adhering to the policy. Fortunately they already fired me so they can blow it out their bottom line
Seriously do it. @Home only makes active port scans on news and occasionally dhcp or mail to look for rogues. They also proactively monitor bandwidth usage so opening up a lot of high access services might get you noticed and shut down. What you are suggesting is offically against the rules and if they want you shut off for any reason, they can investigate deep enough to usually determine what's going on. Then supposedly they'll ask you to shut it down before turning off your service, but if they don't like you they'll just drop the axe. Trust me, seen it.
@Home is garbage. The cable companies are worse. There is really very little good to say about the companies. The service itself, when it works, is overall a good bargain. The atitude of the install tech is due to the cable companies and @Home crying in their beer about being such a horrible company. Expect it to get much, much worse very soon.
