I have been wondering and experimenting with Extended attributes since ROX 2.1.1 added support for them.
Here (http://khayber.dyndns.org/rox/xattr-view-001.tgz) is a simple editor/viewer for extended attributes (depends on pyxattr from http://pyxattr.sf.net). Mainly to be used for testing your filesystem's support of xattrs, but useful for other things.
I added support for xattrs in addition to MP3 tags in my Ripper app. I am mulling over the use of xattrs for Mail, MP3 tags, etc. I may hack Songer and/or MusicBox next.
I'm curious about the speed differences especially for MP3 tags and large playlists.
Share and enjoy.
