Thanks for this information - I'll investigate. I might grow old and die 
waiting until extended attributes are supported on all of the OS platforms 
KDE runs on, so this will help me begin preliminary work.

Yes the attribution may be lost after a file move, but there are some 
imperfect solutions to this problem. 

It just struck me that the file group attribute could be used in a nice way 
for a single machine implementation. You could create, and add your user 
account to, groups like "lowpriority", "highpriority" etc. Then change your 
file properties as needed. Using a theoretical KDE app that could be attached 
to the inode mime type, you could choose a Group name, the directory tree 
would be scanned, and all known mime types would be displayed in a tree view, 
with each mime branch containing under it file for that type. You could then 
click the Mpeg Audio mime type and Noatun would begin playing your matches in 
sequence.

If groups are used, then the file can be moved around the local filesystem 
with no problem. You couldn't have multiple group assignments for one file 
though.
