I dig a little bit into it. running akonadi on nfs home directories is 
not recommended. This is inherited from the underlying database 
(mysql). But it works, nless you don't login on two different 
computers with the same user and start akonadi twice. Network must be 
reliable of course.

As someone on the mailing list pointed out, it is common in enterprise 
environment to share home directories via nfs. So the bad news is: 
akonadi is not enterprise ready (as long as nfs is used). Good news: 
they are working on it.

But nfs is no solution on the long run anyway. With laptops sometimes 
connected to the net and sometimes not you have to choose different 
home sync functionality. For my laptop users I do an rsync via ssh of 
the home drive at login and logout. May be it is time to do it for 
desktop computers as well. If there are not that many files in home 
directory it is quite fast (compressed rsync). And a network breakage 
will not kill your session.
