Problems using shared MySQL database

[Guðlaugur Jóhannesson]

I am trying to set up a shared MySQL database so I can have the same ratings 
wether I listen on the desktop or the laptop.  It was working perfectly, I 
shared the music library through NFS on my lan and through sshfs when on the 
run.  Then all of a sudden (I have no recollection of what made this happen 
since I do not use amarok daily and have been going through many upgrades and 
changed laptops) it stopped working.  I let the desktop build the database 
and then point the laptop to the very same database, using the same 
authentication.  That used to give me a collection on both machines, but now 
it only gives the collection on the desktop.  

In trying to debug this, I let the laptop build the database yesterday and 
found that it created a collection that did not interfere with the desktops 
collection.  After looking at the database, I gather that the songs are 
stored in the table uniqueid.  In that table there is a column named deviceid 
that currently has two values in my case.  What is the purpose of this 
column, and why are all my songs listed twice now?

After reading the collection with the laptop on the lan, I figured that I 
would be able to use that collection also in the office, but I was wrong.  
The collection does not show up.

I am using amarok version 1.4.4 on openSUSE 10.1 (the packages from guru).  
Both desktop and laptop are using the same version, allthough there are two 
different architectures (x86_64 on the desktop but i586 on the laptop).  I 
can play all the songs in the library if I manually drag them to the 
playlist.

Let me know if there is more information I can give.
