Option 4 is not a separate option - it's a possible content
provider reaction to whichever of 1, 2 or 3 takes place. As
Mark pointed out, it has major scaling and trust model issues.
If I'm right and OPES-like boxes are inevitable, maybe the
IETF needs to start pre-emptive work on Option 4.

What about option 4, "information publishers who don't like interference
by transport providers use TLS/SSL to enforce actual end-to-end
transmission of the content" ? As we gain experience in implementing
TLS, this is a certainly a possibility!
How about starting at home by turning on STARTTLS for this mailing list?
