Further to my previous comments; ISPs - not all, but more than one - do 
this anyway. They either buy the only backhaul they can get in Market X 
or, if there is competitive backhaul, they buy backhaul from whoever 
offers the most attractive package for that market or bunch of sites. 
Hence someone buying from Uecomm in Sydney might go to Amcom in Adelaide 
and Perth, while using Nextgen for the intercity backhaul.

Or they might get an aggregator to negotiate a whole package, and leave 
the choice of individual carriers to the aggregator.

If an ISP owns DSLAMs, it already has to deal with these problems. If 
not - if it's a virtual ISP that just rebrands someone else's service - 
then it will leave the choices to its upstream wholesaler anyhow.
