TipTop Tac Toe? 1

SBC is planning to file a new tariff for a service called “TipTop,” which for the first time would cause unaffiliate ISPs and VOIP providers to pay per-minute access charges on their traffic. Jeff Pulver and Om Malik have good blog posts speculating on the implications and SBC’s overall strategy. Is SBC playing a grand game to dominate all communications? My instinct is, not any more than they ordinarily are (which is not the same as “no.”)
