Well yes, the technology is quite cool, I'm not debating that.  The
fact that it works at his mothers house (residential) doesn't
really have any significance.  I don't think you have anyone out
there debating against caping out the upper limits of bandwidth on
what we can get over a single strand of glass.

I look at this article and say "so what".  Now you've gotten the
packets to the house.  Now what?  Wait 10, 15 or 20 years while
companies try to find ways to get content do you?  1500 HD
channels, thats a lot of TV sets.  You can have all the bandwidth
you want, but but until there an actual use for 40Gbps at the home
all you're going to have is the worlds fastest BitTorrent or on net
porn PPV network.


Uncompressed HD TV (typically 1.54 Gbps / channel) comes to mind, for
which there are applications, albeit typically not residential so far.

How practical is it really also that you need CRS-1 at the
residence for this.  I agree with Sean.  Since for most people the
line card alone costs more than the house. :-)
