[AG-TECH] 2.1.2 => 2.2[or 3] Shared Application Migration

[Randy Groves]

Just trying to get this clear in my head - is it true that shared 
applications written for 2.1.2 should work in 2.2 and 2.3?  The 
improvements incorporated in the SharedAppClient class simplify the writing 
of Shared Apps - but am I right in thinking that nothing in the basic 
protocol changed?  If so, is that detailed anywhere?
