Wouldn't having them prepend their AS enough times for prefixes towards you and a low local preference for routes from you (on their end) solve this? That way all the configuration is on their end.

We have a couple of customers that are looking to purchase an Internet connection from us - this will be a BGP feed to each customer as they are multihomed today etc. Normally, we would just supply a full table and let them decide what to do with it. In this scenario, they both wish to use us as a backup provider and wish to ONLY use our network if their primary provider (Cogent) is down. What is common practice for this scenario? We would still prefer to just send a full table and put the control into their hands but I'm also concerned if they will have the technical expertise to accomplish this.. On their side, what would be common practice? I've been looking at conditional BGP advertisements using route-maps but don't believe that's the best solution.. Thanks for your input.
