There are several independent DSL sellers too, like DSLExtreme etc, which also have no caps.
ATT would only be able to put caps on DSL where there are no CLECs at that central office (rural areas). Otherwise the CLECs will have a windfall, advertising no caps DSL to residential customers.
True, DSL Extreme would have a field day if AT&T started capping. They already have excellent pricing and a lax AUP.
The question is, if all of AT&T and Time Warner's heavy users switch to DSLExtreme, can DSLExtreme handle the traffic? My worry is an overabundance of "hog refugees" would force DSLExtreme to move to a metered system. They'd still have good opportunity to be a little more fair about the allowances and pricing though. -- AT&T U-Hearse Your funeral. Delivered.
