I'm happy to add this one to the list of things that you really must
not consider strong.  Which brings me to another point:  It's
probably worth using RFC 2119 verbiage when we enumerate what's
considered weak or strong.  I've made that change in the latest
version, and would actually be tempted to change this further to say

	SSLv3 SHOULD NOT be considered strong.

I also wonder if it's worth saying a word about MD5-based certs.

Not that I'd know.
