Thanks for the explanation.  As there is a graphic part to this process of 
"marking as read", can't that be done whilst the actual update to the email 
storage is queued to be done once the "channel" becomes available again.  Is 
this "single channel" design a bit limiting, should there not be multi-
threaded access in this day and age? (i don't know anything about akonadi 
really so i'm just throwing ideas in the air)

Sounds like a possible solution or work-around. I presume the idea of caching 
the emails in the old "Mail" folders was dismissed.
