Development of Creative Commons licenses

[peter <dslt03 AT pacbell.net>]

To whom it may concern,

	I read an article on slashdot.org by one John Dvorak (link 1) the 
discussion sparked on the slashdot forums (link 2) peaked my interest. 
I read a post by a person with the online handle Mrs. Grundy (link 3 [to 
the comment]) that prompted a thought relating to other work I've been 
doing.  I'm currently an active developer on the project Semantikos 
(link 4), needless to say I'm familiar with the concept of RDF 
meta-data.  I'm also familiar with the process of inheritance that is 
embedded within the standard for RDF.  It occurred to me while reading 
Grundy's post that the very openness and flexibility of the Creative 
Commons license and it's ease of inheritance, might prove a stumbling 
block for royalty disbursement to the authors of a work.  For example, 
take an authoritative work such as a song.  Under a Creative Commons 
license it would be possible to take pieces of that song and remix them 
to form a new work.  That work would also be likely licensed under a 
Creative Commons license, thus it too could be remixed, changed or used 
in a variety of ways.  But suppose in some iteration of our infinite 
series of re-use someone wants to publish a derivate of the original 
work for profit.  How would someone go about contacting the author for 
such a purpose?  Also given the rather complex parentage of any 
derivative work, wouldn't it be prohibitively expensive to license a 
Creative Commons work (I'm assuming free distribution for non-commercial 
purposes, but that the license requires the permission for commercial) 
for commercial use?
