Re: [Coin] New Version Notification for draft-kutscher-coinrg-dir-00.txt

Thanks, Phil,

That was just in time.

We have just submitted an update that reflects some of your points (see 
other message).

Of course, there is more to be discussed — let’s do that on the list 
and in Singapore.

Thanks,
Dirk
