Any hardcore gamer would tell you a 100ms connection is pretty detrimental to your game performance (hence LAN parties).
I have a few VoIP installations for small businesses, and I generally don't want to do them if I can't keep latency under 50ms. It starts to get very annoying before 100ms (as in the "satellite link" effect).
That's why I think queue management algorithms should not be tuned for overused DSL links. While that may be relevant to those who are stuck with them, the buffers in your DSL equipment will kill your latency anyway. Already LTE connections have latency under ten milliseconds if you can avoid keeping them filled.
I agree 10 ms per hop sounds like almost an order of magnitude off. The people for which that is relevant won't be helped by this anyway.
