Joe

a capability to receive would indicate _who_ you want to receive
packets _from_.

what we have now is the right to be bombarded or not. different.

the problem with many capability based systems is that they require
the sender to get a cpaability to send to a receiver which either
moves the problem to the capability server for the receiver which
means that then gets bombradred (see papers on denial of capbiability
attacks)
or else puts the receiver at the mercy of a 3rd party (probably
distributed and overprovisioned) cqapability service - i.e. less net
neutrality

requireing a receiver to control who can speak to them as a
fundamental part of connectivity (I have a paper i might submit to a
hot workshop about one approach to
the implementation details for this if i can get around to it...)
is an altogether more neutral scheme...
