Re: detailedDM doesn't work

[Yuri Pryadkin <yuri@who.isi.edu>]

Sarah,

there is no easy way to fix it because there have been too many
changes to multicast/interface code/lans.  Shuqian is right that it is
not going to be supported in b5.  I think it's easier to rewrite
detailedDM from scratch than to fix it.
