Well the solution there is that the hosted stack's message path is *not* 
integrated into that of the host stack - the problem then goes away :)

Instead, think of a stackview control as creating a transformed space 
within a stack which is filled by another stack. It is a purely visual 
thing rather than structural.

Stacks can still communicate in all sorts of ways - for example, you 
could have substacks embedded in the mainstack so the messages flow in 
the current way you'd expect; or you could use a library which enables 

Also, there's also the option to add syntax allow a stack to send 
messages to its 'host' - whatever that might be. (This idea of 'host' 
isn't unique to the idea of stackview - exactly the same idea is present 
when you think about embedding a stack in a web-page in the HTML5
