Max--

Haven't looked at this fully yet, as I'm just glancing at it before I head out 
the door, but a couple of things I saw off the bat:

User-defined labels:  the concept of labeling is something we've kicked around 
for a while now.  This would solve problems people have right now where 
there's a situation like having "Paul Simon" and "Simon and Garfunkel" (not 
the greatest example, but you get the picture).  In many cases the user wants 
to keep those artist tags in the file, but be able to find it by looking for 
Paul Simon.  A label that could be assigned dynamically to tracks and contain 
a subset of user-chosen items would be great (think of Gmail's labels).  If 
you come up with a good way to do labeling, then you could not only have 
labels for songs, but you could automagically create labels that cover 
available parts of the collection and use the functionality for either.  So 
as you think about device labels, keep song labels in mind too.

ATF and dynamic collection:
You are correct that ATF associates a unique value with a file to keep track 
of it, even if amaroK is closed, without requiring services to be constantly 
on and watching file changes (have fun reinventing the wheel, Gnome 
multimedia SoC hacker wannabe).  What you got wrong is that the 
file's "primary key" as it were is not the absolute file name/URL.  After 
all, this is what can get inconsistent!  Relying on the URL would solve 
nothing whatsoever.  The file's primary key is an 8-character randomly 
generated string embedded in the file's metadata.  This is then used to 
figure out where files moved around to, and to update the absolute file 
name/URL in the database.  How you'd use this with dynamic collections is 
probably to have the device identifier as you mentioned, and then have ATF 
lookups return not just the URL but the device identifier as well.
