The value network in the music industry in the (i) physical and ii) digital worlds

You have me completely confused. Are you asking for the sum of the
probable selling price the music related web sites world wide. If so
the physical world is small as net access is typically leased rather
than owned. Esentually everything is digital on the internet. The
sound card in the listener's computer converts digital music to
analog.
 Perhaps defining "value network" would be helpful.
 I have a friend who works at home (sub contractor) for
www.radioio.com, He has a large collection of vinyl records, but I
belive nearly all the music he uses is on cds, mepeg 3 or other
digital format. My friend's facility could be valued between $4000 and
$200,000 depending on who did the accounting. Please comment, refute
and/or embellish.  Neil
