i want weak protocols restricted to LANs or at most campuses or ISPs.  that
means UDP/137, UDP/139, and TCP/25 at the moment.  stay tuned, we might be
adding more.  oh and as long as you're considering whether to restrict
things to your LAN/campus/ISP, i'm ready to see rfc1918 filters deployed...

Does that include DNS?  That's a pretty weak protocol.
