Certainly video is one of the most bandwidth intensive applications. I
don't deny that a < 1 Mbps video call is both less common and consumes
less bandwidth than an 8Mbps HD stream. However, if Americans had access
to symmetric connections capable of reliably making HD video calls (they
don't, in my experience), we might be seeing video calls as a common
occurrence and not a novelty. I think the state of usage is a reflection
on the technology available.
If the capability was available at an affordable price to residential
consumers, we might see those consumers stream movies or send videos
from their home or mobile devices via their internet connection directly
to the recipient rather than through a centralized source like Disney,
NetFlix, Youtube, etc. Video sharing sites (like youtube, vimeo, etc)
primary reason for existence is due to the inability of the site's users
to distribute content themselves. One of the hurdles to overcome in
video sharing is the lack of availability in affordable internet
connectivity that is capable of sending video at reasonable (greater
than real time) speeds.

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.

While that is true a lot of the time (especially for eyeball
networks), it is less so now due to social media. Social
media forces the use of symmetric bandwidth (like FTTH),
putting even more demand on the network,
Oh yes; clearly, Twitter will be the end of L3.

Could you expand a bit, Mark on "Social media forces the use
of symmetric
bandwidth"? Which social media platform is it that you think
has a)
symmetrical flows that b) are big enough to figure into
transit symmetry?

Applications like Skype and Facetime (especially conference calls)
would be one example where an application benefits from symmetric
(or asymmetric in favor of higher upload speed) connectivity.
Cloud office applications like storage of documents, email, and
IVR telephony also benefit from symmetrical connectivity. Off-site
backup software is another great example. Most residential
connections are ill suited for this. I believe these applications
(and derivatives) would be more popular today if the connectivity
was available.
