We may want the alto protocol to allow the requester to specify which
type of ranking/preference it needs. Note that this doesn't mean we
need to standardize any algorithm.

Yes, there's been some discussion about how to deal with the fact
that
different applications may have different requirements for peer
selection -- e.g. file-sharing would benefit most from connections to
peers with higher uplink bandwidth, while realtime communications
applications would probably want to chose media relays with the
smallest
delay.
I remember someone suggested that a way to address it could be to
simply
provide a means for the querying peer to specify what parameters it
would like to have optimized (delay, bandwidth...) and let the ALTO
server use such information in its processing. However, AFAIK, no
solution proposals at this time do anything like that.
