Policy-based routing is evil? Discuss.

I'm having a discussion with a small network in a part of the world where bandwidth is scarce and multiple DSL lines are often used for upstream links. The topic is policy-based routing, which is being described as "load balancing" where end-user traffic is assigned to a line according to source address. In my opinion the main problems with this are: - It's brittle, when a line fails, traffic doesn't re-route - None of the usual debugging tools work properly - Adding a new user is complicated because it has to be done in (at least) two places But I'm having a distinct lack of success locating rants and diatribes or even well-reasoned articles supporting this opinion. Am I out to lunch? -w -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
