I stand corrected - it seems I do in fact know someone who's observed this technique used to send spam, albeit in the past when POTS dial-up pools were the de facto access method for the masses and before the technical and commercial maturity of the botnet business model. I still maintain that even if it's being used today, it's rare, and essentially a corner-case. This isn't meant to detract from the novelty and creativity of the paper in question, but rather to posit the view that it isn't necessarily something for operators to get too worked up about, in the scheme of things. ----------------------------------------------------------------------- Roland Dobbins <rdobbins () arbor net> // <http://www.arbornetworks.com> Sell your computer and buy a guitar.
