so you're saying you can support 2x dsl, for the cost of a second line,
setup and equipment? (I don't know what cisco you are referring to, but
cost and ease of use are certainly factors -- I think the real point is
why don't you sell the stuff preconfigured so people who want 2x or 3x
bandwidth can get it without integrating)
