Symmetry isn't totally arbitrary. In many deployed access technologies, scaling head end send speed is easier than scaling user end send speed; sometimes there are settings to increase upload speed at the expense of download speed (ex annex M for adsl2), but sometimes it's an inherently asymmetric system.


Even so, it would be a good thing for ISPs to change that infrastructure.

That won't happen until there is a fiscal incentive for them to do so, so let's not be afraid to give them one.
