@Lord_Palethorn:
But wouldn't squid help lower the http traffic? (youtube / ustream / steam / ..) so there will be more bandwidth available for gaming?
It will to a certain extent but Squid can cause problems for online games that authenticate through http but not for the actual game traffic (Many F2P games do so and I've had it break Blizzard Battlenet as well).
Furthermore, you will only save the bandwidth if the data set is repeatedly accessed.
