Uh, it was produced and paid for by IXPs for the intention of promoting
IXPs.  Why do you have an issue with this?

Call me glib, but if you can get the association of PNI providers together
to create a movie about what PNIs are and how they work, I'd be ok if they
glossed over IXPs.

ECMP?  Per packet load balancing, even?  Again, the point they were making
is that the path from A to B is not particularly important to the data
being transferred.

Look, the creators of the movie had 5 minutes to explain something so that
regular Janes and Joes would understand, rather than 1 hour to give a nerdy
in-depth explanation of the nuts and bolts of IXPs.  Personally, I think
they did a rather good job.
