  I'm on network X with ISP Y.
  ISP Y connects to research lab Z, research lab Z has tons of multicast.
  With mrouted, I'd make a DVMRP tunnel. Z isn't doing DVMRP anymore,
suggests PIM v2.

  I see /usr/pkgsrc/net/pim6dd, will that work for IPv4 multicast?
  (As emitted by IETF...)

  I happen to already have V6 over gif to Z. Perhaps I should just try

multicast people...
