dunno :-)

the decoding layer breaks the input into a stream of messages. the
processing layer processes these commands by calling the repository
layer then returning response messages. these response are then
encoded into a byte stream by the encoding layer.

implementing a new processing layer means creating an implementation
for each IMAP command. this gives a lot more control and flexibility.

implementing a new repository layer should mean less work but forces
you to reuse the processing layer and to implement the current
repository layer API. IMHO this is too general and you may find
difficulties creating quickly a good implementation.
