Of course, from a technical point of view I am all for symmetrical 
connections as well.

>From a commercial perspective I think that it's hard to recouperate cost 
from a 10 meg symmetrical connection when the customer is running p2p and 
is using most of that bw 24/7 and is only paying $40 or so for that 
pleasure. Yes, one can degrade that customers performance by ratelimiting 
or such, or prioritizing other customers traffic or something else, but 
the 90/10 rule saves some of it, the problem is when the 90% start doing 
the same, then the flat rate business model is a problem and does not 
scale.
