Re: [Dyncast] Fw: New Version Notification for draft-liu-dyncast-ps-usecases-00.txt

["Joel M. Halpern" <[e-mail]>]

This problem statement draft seems to assume a particular approach to 
the solution.

It is not at all obvious, absent the assumptions, that one wants to put 
the information into routing at all.  There are multiple approaches that 
address the problem that do not require the use of anycast addressing or 
injecting the application placement dynamics into the underlying routing 
system.

Yours,
Joel
