I'm generally OK with this apart from the requirement 'visually  
displayed..', I'm unsure if specifying this explicitly is the best  
option - what if the application does not present itself visually?  
Maybe it should say something like - 'in the same manner as the  
application presents its interface (eg visually, aurally , etc)

Visible again - I understand the context here but it seems ambiguous  
to me

Agreed

Can we not just mash this up with 1 above?

Agreed.
