I'd be very much for A except that I'd like somehow a failure to resolve
due to a dnssec problem to return a pointer to something, somehow
that informs the user as to what went wrong and what to do about it.

All versions of cerowrt prior to 3.10.36-3 potentially had heartbleed
in the https admin interface, and also possibly hostapd (though I
don't know how to exploit it). The optional wpa_supplicant, openvpn,
strongswan, authsae packages also were affected and a few others I
forget.
More scarily - from a large deployment perspective, things like the
radsec radius backend also use TLS security to carry authentication
info back to a radius server.
All of openwrt, dd-wrt, etc from Attitude Adjustment to trunk to about
12 hours after the disclosure were vulnerable. Patches went into the
relevant repositories but it's going to be very hard to push updates
out to the field, since no update mechanism exists for most embedded
products.
Boingo has sent out a mail to all customers saying they were not
affected, but I do worry a lot about the overall security of
enterprise wifi and 802.1x ethernet networks in general.

I'd like more probes and defenses in general, notably things that detect
dns amplification attempts and send them somewhere to be collected,
some sort of universal moon worm attempt detector/reporter, and the
equivalent of a rbl database for attacks and potential attackers.

Concur. On the one hand I was happy with the idea of dnscrypt, but not
happy that the backend couldn't do dnssec right.
