some probably do. but there's a definite difference in the markets
that each are geared at.

none. but if peering is an issue they buy a line from a national isp.

the irish ISPs do.

look, if BigTelco sees enough traffic from his customers going to
irish destinations, then maybe then it might be enough of
a financial motivation for them to peer at INEX.
These BigTelcos (and by BigTelco we're not talking small fry like
Eircom) probably do not even peer their /own/ irish traffic in
ireland, or maybe customers of theirs have /paid/ for their bandwidth
to go directly into the UK.
In those cases, how are they going to peer at INEX?

Yes. most definitely...
it'd be nice if INEX became a european super-peer - but it has make
sense, and it doesn't.

because the most direct route would be:
murpynet - INEX - ryan
murphynet - GlobalFoo - INEX - Ryancom
murphynet - GlobalFoo - INEX - Foonet - Ryancom
ie the most direct route does not involve upstream providers peering
