Well, there's basically only 5 networks of any size that don't 
participate (Telstra, Optus Singtel, AAPT TNZ, MCI and SPT (AS9942) who 
aren't that big).

So, clearly it's not a big issue.   What's interesting is the kinds of 
people that DO participate (Asia Netcom, VSNL (Oz only) etc).

It's an issue.   But overall it's not big enough of one.   We all gain a 
lot more by peering together than not.

Yeah - I can understand why MLP is not big elsewhere (we peer in the US 
so I do the peering there - it's very different, but also the traffic 
levels are very different.   

We all share a lot of content here and so the savings amongst 7 of the 
10 top broadband companies in Oz make it all worth while.

MLP is what works here - the GoF believe that their transit is special 
and won't peer with anyone else in Oz.   It's partially a government 
mistake from the late 90s.
