I have that as well. :)

Syncing the metadata indeed is something that is not easy.

I just sync the maildir folders, the (local) addressbook, kmail 
configuration (not the akonadi config and database!). For IMAP I don't sync, 
the sync happens through the server. Yes, it means that if you didn't use 
the laptop for a longer time, it will download some mail...

In theory you could sync the whole database file and configuration, but you 
have to make sure the akonadi server is shut down on both source and target 
machines before synchronization. I never tried it, so cannot guarantee the 
success.

Yes, initial import is long and will take a lot of memory (in case the 
memory usage doesn't go down after import, you can restart the server).
