Do you think we are in for some 'truth in packaging/labeling' laws
regarding what you are 'really' getting with a "10Mbps" connection? Will
this have to be statistically sampled and various legal weasel words
inserted?
Do any of the current network providers include bandwidth guarantees? How
do they do that? I can imagine scenarios where even a dial-up connection
would slow down due to traffic/use on the host. What does it say in *your*
fine print?
Presumably internet access providers will not be the used car salesmen of
the 21st century ("The only other people using this port are little old
ladies who just use it to download Oral Roberts' sermons.")...
