Apps messaging: Gathering requirements

[John Taylor]

Hi again,
Apps Messaging has gone pretty quiet - in particular no-one has  
disagreed with my summary of a two weeks ago...which I guess is a  
sign that we've come to some conclusions.

I think it would be useful to our discussions if we had some idea of  
the problems we want to solve with application messaging.  This  
doesn't need to be a definitive list, just some concrete examples  
that can guide our thinking.

I've seeded the list with some of the tasks we currently accomplish  
using PLASTIC.  I'd be grateful if others could add use cases that  
are of interest to them (especially someone who is familiar with DS9  
could add something similar for XPA.)
