We are interested in knowing the growth of traffic that is:

  Users -- ISP -- IXP -- ISP -- Users

That includes direct webrtc traffic, direct gaming traffic, SMTP, SSH,
VNC, RDP, ...

(Whether this includes cases like me, where my web site is at my home office
is a big question.  In a CDN world, I'm supposed to host that elsewhere.)

Sure, CDNs can have private peering with ISPs.
This is a common activity for Netflix, akamai...
It is usually a win/win where the CDN provides servers that go into an ISP
hosted cabinet.
