What is the difference between a transit provider and an access provider,
specially in the consumer space?  Why is a transit provider expected to
deliver the bits, but the access provider isn't?  Since the bulk of
Internet access is actually provided by wholesale providers (e.g.
AOL/Earthlink buy wholesale modem access from UUNET/Level3), who is
the access provider and who is the transit provider?
And how do you handle the situation where a provider is both? UUNet, for example, sells LOTS of T-1 lines to non-ISP businesses, and sells retail dialup services to consumers. Sure they also sell wholesale bandwidth and wholesale dialup services to ISPs, but it's not their whole business.

The problem isn't "someone else's problem" for anyone.
