The only thing we are missing in Akonadi is the "sliding window" that allows 
to fetch only first 100 or so message headers and then fetch another 100 when 
requested. Minor adjustment to the expiration policy would be needed too to 
make it able to completely delete messages older than X days.

I just quickly glanced into htop to see how much my Akonadi is eating right 
now - I'm sure most people don't have 3 massive mail accounts, 5 calendar 
accounts and everything compiled in full debug mode. For users with one gmail 
account it's probably around a hundred or two hundred megs? Not saying we can 
do better, but we are doing reasonably good IMO.

Nowadays we only use DBus for simple calls here and there. Notifications go 
through the binary protocol.

I see. Well, contributions are welcomed, I suppose :)
