[e2e] TCP "experiments"

the nice thing about a lot of the big cloud/web service outfits
is that they run a huge _range_ of applications so a point solution
tcp optimised for just one thing that
harmed the common case uses of TCP would be ruled out -
if you think about the mix of map/reduce,
video streaming, social net, searches, gmail, gfs, google docs, etc etc
(and similar mixes for microsoft bing + hotmail + azure etc;
and similar for apple iCloud, appstore, and similar for,
oh, i dunno, maybe even facebook),
then I doubt very much we'd see them do something
as narrowly dumb as people seem to imply here
(or deploy someone else's dumb narrow hack either)....
as for impact between different cloud/web service providers
(e.g. google being smart enough to optimise a TCP hack for all that stuff
but still harm Amazon's traffic for book/cd buying, EC2, cloud music player
etc etc, that would be incredibly ingeneiously dumb,
but also unlikely, since a major google's revenue depends on
people finding stuff on _other servers,
and finding those other services useful,
so it would be kind of silly to auction advert space to the highest bidder
iand deliver those adverts in a way that broke the advertised things....
[I suppose you could deliver adverts that broke TCP services to
servers that hadn't paid you to advertise them - that'd be pretty
super duper whacky type of cyberwarfare game some folks at the NSA
probably have fun thinking up.....
maybe Huawei could deploy some DPI-based filter to harm succesful businesses only
so as to bring down the whole capitalist imperialist western civilisation....oh no,
wait, they need our net to work so they can sell us their routers...
