Hello Jari,

Very minor, a missing period on the bottom of section
2.7.
        "would first
be converted in other1.example net to"
should be
        "would first
be converted in other1.example.net to"


Also, sorry to come in so late on the disccusion but
just wanted to add a comment on 2.7 Realm Construction as it pertains to
roaming.  The proposed method seems to be opposite of what I see in
practice today.  Typically what is commonly referred to as the prefix
domain, the portion before the '!', is used for the intermediary domains
where the suffix domain, portion after the '@', is used as the home domain.
 Not only does it make it much more readable since the username@realm
is preserved at the end of the string, but it also takes away the need
to reorder the parts when proxying and is simpler for an intermediary domain
to just strip off its own domain in the front and the first '!' and pass
on the rest of the string.  

So in your example where you have

        other2.example.net!home.example.net!user@other1.example.net

in practice today it would be written as

        other1.example.net!other2.example.net!user@home.example.net

and sent from other1.example.net as
        
        other2.example.net!user@home.example.net

and sent from other2.example.net as

        user@home.example.net

Not sure it really makes much of a difference since
both are recursive just seems a little cleaner to me...
Thanks and regards,
Josh
