A couple of suggestions/questions regarding the draft and the recent
minute:

1.-Do we want to provide for failure recovery in the migration/replication
protocol? I know that in most cases we should be sending differential
changes to the filesystems but I keep thinking of the case were we have a
full (intial) migration/replication of a file system and one side involved
in the process fails; do we want to have some type of migration
checkpointing?

2.-I think striving for a efficient bandwith utilization is a great idea so
I wanted to make the group aware of recent work in this area that may
relevant to the design of a a bandwith efficient migration replication
protocol:

http://www.cs.ucsd.edu/sosp01/papers/mazieres.pdf

I think the bandwith-saving ideas presented in this paper may work great in
migration/replication. What do you guys think? I am not so sure if any
patents cover these ideas there, though.

Certainly.  Look for minutes on the WG alias in a few minutes,
and here's the rough draft I sent to the design team.
