ok.. think about it. Imagine 2 layers. Top layer are the Big Telcos,
second layer are the national ISPs, via, esat, etc..

The second layer are customers of the top layer for extra-ireland
traffic and the second layer peer amongst themselves at INEX.

What is the use of the top layer peering at INEX too? Esp. as the
top-layer, to my knowledge, do not operate any national networks of
any significance. (maybe their POPs, that's it.).

If you buy bandwidth from the top-layer then you are probably already
big enough to peer at INEX yourself.

exactly...

imagine:

Murphy Net - peered at INEX. have lines through GlobalFoo.
RyanCom - peered at INEX. have lines with BigNet.

what would be the point in BigNet and GlobalFoo peering at INEX? it's
not going reduce their traffic cause the traffic is already going
over INEX.

The BigTelcos, and many more, are already peering with each other in
places like LINX and AMS-IX. (Eircom and Via are also AMS-IX peers).
