They get the speed without the price because a) they don't have to comply with
any existing standards, b) everything is done with a DSP, c) it's not 9600
full duplex, with only a small backchannel I believe.

Why has nobody used it up till now?  Someone at CompuCom got a bright idea.
CompuCom has been around for a long time, so they have had plenty of time for
research.
