Sorry, probably I missed your point - how content information can be used in
peer selection (traffic optimization) ? 

Let's consider a use case when ALTO has no knowledge about additional peers
(such as cache) to "enrich" list supplied by client for optimization. 

ALTO receives list of peers ( and their characteristics) from client and
should send back ordered ( and probably filtered) list of the same peers. 

What kind of information to be used in this process?

IMHO, ALTO needs to know peers characteristics (leeacher, seeder,
firewalled, etc),network topology, utilization, some traffic business rules,
but I fail to see how content information can be useful here at all....
