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. > 2. Should the protocol specify how to handle a <body> > in a <message> containing whiteboard data?

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. > Thanks, > Joonas > > __________________________________________________ > Do You Yahoo!? > Tired of spam?
