As noted on Slashdot, if you were to post a CR fix service installed at
http://<yoursite>/default.ida, which would run a remote command on the
connecting host, to de-worm and patch the offending box, who's
culpability is it if your site is connected to and the patch is run?

This is stretching the case a bit, but it's an interesting hypothetical.
Frankly, I'm moderately convinced it's not a bad idea.  Not quite a
Cheese Worm -- it doesn't actively hunt hosts -- but widely distributed,
an effective antidote.

Personally I favor the "Debian GNU/Linux install" service model
myself....
