I have no idea but just a guess that the xml file is transported to
teh iPod as well and there it is the datafile as well?  I use to use a
java based music sharing site Furthur and that was their way of
working.  I had close to 1-TB of shows and each concert and song was
in XML.  They also had other files for legal bands allowed to trade,
videos and other stuff as well.

for small format stuff it's great but measurable in either megabytes
or 100,000 lines it loses it's appeal.
