RE: [RRG] Are host-stack modifications allowed or disallowed ?

|Why should these routing decisions be mutually exclusive? Why must a

First, it's not a protocol issue, it's an architecture issue.  As I
mentioned previously, hybrid forwarding architectures that support both
hop-by-hop and specialized forwarding schemes have been proposed and have
been widely ignored before.  Please see RFC 1668 as an example.  Please note
the authors.  ;-)

It's definitely not out of the question, but to assert that folks really
want this now implies that there's been some change in conditions that would
make this feasible from a deployment and business model perspective.  I
certainly haven't seen any indication of that.  Why now?  What's changed?
