It should not be lost. It can be lost in a case when the other side
loses connection, the server goes down or thing like this.
I guess would not recover from such situation anyway.
But, if you really want to get a reply 'yes, I got the data', you should
use <iq> instead.

Personally, I would not allow that. Actually, personally I would use <iq>
stanzas and allow standalone implementations (which do not have the IM
client, only whiteboard) to set priority to negative and not receive
messages at all.
