Modem Accelerators?

An Anonymous Coward asks: "I was browsing on the web and came across a reference to Coastal Web Online's claim of a modem accelerator Apparently it is a service which is supposed to make your modem 3x faster. Is this possible? I've already got a v.92 modem and I thought it already did compression. It is possible it is a proxy doing some compression on white space in HTML or something, but I don't think so, since it apparently only works with Windows 9x and Internet Exploder. For $8.00 a month ontop a the dialup access sounds kinda snake oilish. Does anybody on Slashdot use the service? Would they recommend it? This sounds remarkably similar to the old idea of 'waxing your modem'. Am I missing out on something here?"
