Please look into real world, not idealistic.
Servers have sometimes long timeouts (nobody says they can't), don't do
any sort of pings (nobody says they must) and many people have unstable
connections, even on ADSL, but much more on wireless, especially when
moving aroud.
It's a common things to loose messages on Jabber for people with bad
connectins. The good thing is that when one comes back, the old
resource is kicked (with reason: reconnected) and the user is
notified... and after some time, users learn that after other party's
"reconnect", they must re-send what they have posted.
If this is not the case, users become confused and will start to think
Jabber is unreliable. And what more, they will rightly do so.
