Blake,

None of those applications come close to causing symmetrical traffic
patterns and for many/most networks the upstream connectivity has greatly
improved.  Anything related to voice is no more than 80 kbps per line, even
if the SIP traffic isn't trunked (less if it is because the signaling data
is shared).  Document sharing is not being impinged, on my residential
account right now I've uploaded about 30 documents this morning including
large PDFs and Power Point presentations.

Off site back up is one use that could drive traffic, but I don't believe
that the limiting factor is bandwidth.  We looked at getting into that
business and from what we saw the limiting factor was that most residential
and SOHO accounts didn't want to pay enough to cover your storage &
management costs.  In our analysis the impact of bandwidth on the consumer
side adoption was basically zero.  There is no expectation that back ups
run instantly.  Having said all of that, even if hosted back up became
wildly popular would not change the balance of power because OTT video is
both larger, especially for HD streams, and used much more frequently.
