V.92 - Is it Worth the Upgrade?

Moo T Foo asks: "Has everyone heard of the new V.92 protocol? It looks that there is little to no support from the ISP's to even upgrade for this standard. What's the point? DSL is dominating the market place for consumers. What do you think about this new protocol? And is the V.92 worth the upgrade if no one will support it? Check out 808hi's site for more background on V.92." It sounds like a fairly useful upgrade. I'm surprised the ISPs aren't already jumping on it due to features like "quicker handshaking, and call-waiting/modem-on-hold capabilities" which can only benefit their existing customers.
