No I'm not suggesting basing it on what a provider is currently advertising. But rather on what the provider has registered and is authorized to announce. The set of authorized routes may be the same or a superset of what the routes the provider is currently announcing.
If you want asymetric routes, you can register and authorize traffic via either route; and then dynamically announce which route you want to use moment to moment.
How about not storing filter-information in configuration space, rather do dynamic lookup via directory-lookups (that could driven by RPSL via LDAP ) ? Since a BGP-update is done just near-real-time a split-second lookup would certainly not delay the routing-table calculation, but rather provide a centralized method to maintain policy information. These things change anyway so fast that accuracy is difficult on daily update basis. It would also allow very fast elimination of networks that do harmful things (spam, DOS, etc..)
