If I send a message to someone who is offline for a month, I may suspect
that the message could be dropped.
But imagine a situation like this:
I send a message to romeo at example.org/Home with a AMP rules defined as
in previous post. Romeo is now offline... installing a new Jabber
client. He quickly sets up everything and connects as
romeo at example.org/AtHome.
I may not even notice this small change, but my message will be deferred
and after some time silently dropped.
I think these situations are a bit different.

I have a friend who is an admin of a computer network which I use.
Sometimes it's easier for him to solve my 'problems' when he's at work.
So I'd like to send them to his 'Work' resource, even if he's not there
at the moment.
Now let's say that I just sent my message, although 'Work' is not
connected right now. But I don't know that he just went on 1-week
holiday. In such case, I'd like to have a rule saying "if he doesn't
connect at work within 24 hours, deliver it where possible".

So, in general, it's a situation when a message it's more convenient for
a person to receive it at particular resource and is not urgent, so it
may wait a bit, but not too long. And it's better to get it somewhere
else than to wait too long.
