I've been able to negotiate peering+transit relationships with providers, but only by threat of total revenue loss; ie "we currently pay you $x million/year; we want your on-net routes as settlement-free routes, and will continue to pay for off-net transit traffic. Otherwise, we will be transferring all that revenue to your competitor, X"
If the customer is taking these on-net routes via an exchange point or private peering arrangement, this should be fairly easy to do. If they choose to take it over the same link as their off- net service, not only does the provider need to support a visible way in which these services can be separated over the same wire, but it may also not make much sense for the customer as there is potential for on-net traffic to hog the link, making the case to upgrade the link for traffic that may not necessarily incentivise them to do so. But it's hard to judge this one, especially if the ISP is large with tons of other on-net customers "talking" to the customer negotiating such an arrangement. I can see ISP's accepting to do this if the ratio of on- net:off-net traffic is disproportionate, in favor of more off-net traffic.
This tends to be effective only for content providers, though, where the outbound traffic dominates, and you don't care if the inbound bits are coming over the "pay for" pipe vs the "settlement free" pipe.
It's also mostly useful where the ISP is sufficiently large in a meaningful way for their on-net routes to make any sense to the downstream customer negotiating such an agreement.
If you're an inbound-heavy shop, though, this won't really buy you much benefit. (And, if the revenue point isn't in the $x millions/year for the transit provider, they're more likely to just shrug and say "too much hassle...please, go be a headache for our competitor" rather than configuring a dual relationship like that--so it really only works for higher-volume relationships.)
Maybe what you meant to say is "if the revenue point isn't high enough" :-). Relatively, different ISP's may be kings in their part of town, but still be small enough to accept fewer dollars for such a deal. On the whole, I can envisage cases where trying to fix this "peering with customers" issue can end up causing inadvertent competition with exchange points. Mark.
