If it's like that, then something else must be seriously wrong with a
lot of DSL.

>From personal experience, I can either upload at full capacity or
download at full capacity, but never both at the same time. Download
speed cuts in to upload speed a but, but upload speed cuts in to
download speed drastically, and when uploading things, latency goes to
hell in a handbasket (making ssh unusable it's so bad).
Some time ago I began investigating traffic shaping to better share my
resources via BitTorrent (for things like Slackware ISOs and such)... I
never actually implemented anything, but a common thread I seemed to see
in people's comments regarding traffic shaping uses was to solve this
upload-kills-the-connection problem so many DSL users seem to have.
I can't offer anything more than anecdotal evidence that this is the
case... so take it for what it's worth. :-)
