That's an assumption that's not always valid.  There are cases in
existence now where a service provider *pays* the ISP to run a local
mirror, leading to

client --> Internet -> ISP -> Intercept -> Internet -> Server1
                                        ->  subnet  -> Server2

It would be entirely possible for the service provider, having paid
the ISP not to get traffic from the ISP's clients, to block that
traffic - or limit its bandwidth.

Consider the progession:

client --> Internet -> ISP -> Router -> 56k  -> Server1
                                     -> T3   -> Server1

client --> Internet -> ISP -> Intercept -> 56k  -> Server1
                                        -> T3   -> Server2

client --> Internet -> ISP -> Intercept -> Internet -> Server1
                                        ->  subnet  -> Server2

What is the fundamental difference between choosing the best path and
choosing the best source?  Arguments that the latter breaks the IP
model are simply arguments that the IP model is broken for today's
Internet and will be even more broken for tomorrow's.  The IETF can
fix the model ... or leave that to someone else.
