vdsl signaling speeds go out to about 52Mb/s yahoo broadband (softbank)  
sells this in japan as 23Mb/s down 6 up service. some adsl modems can
train as high as 8Mb/ down for short distances. most adsl providers in the
US have a least 1.5Mb/s down 768k up available as part of their service 
offerings.
