Did you discuss the migration path? I'm asking because when we introduced 
Akonadi migration was a disaster (despite Kevin Krammer's heroic effort to 
write a migrator). We shouldn't repeat the same mistake. In particular, you 
shouldn't underestimate the effort the migration takes. I suggest to not write 
the migration after Akonadi Next is done, but to write the migration 
(including real-world tests) alongside Akonadi Next.

The last time I had a look at KMbox it wasn't fit for general consumption. Its 
API leaks implementation details (i.e. internal data structures) which makes 
it almost impossible to improve its internals, e.g. the IMHO insane memory 
consumption.

I have mbox folders with 100's k messages and KMail 2 can hardly open them on 
my 2 GiB laptop despite David Faure's and others' memory optimizations. KMail 
1 could open those folders using only a fraction of the memory KMail 2 uses.

I considered writing a KMbox2 to improve the memory consumption, but I never 
got around doing it.
