Yes yes, it's of course technically possible. It's no problem to saturate
a 100M either if you have a decent computer.
Still, if you take 10.000 random consumers with 10M/10M pipes you'll see
that this population as a whole only has an average peak of a few hundred
kilobits/s per user. A few percent will do 5-10M sustained a lot of the
time, but a lot of them will be totally quiet most of the time.
