Fwd: Offline operation of a Web application

The question below made its way to me and it seems to have  
significant architectural implications, so I'm looking to see if it  
is/has been considered by the TAG or others at W3C.  In particular,  
has disconnected operations

1. come up in TAG discussions?

2. been addressed in other W3C work, for example with the mobile Web?

TIA,

Ken
