I run a site that is a database of books and other printed media (see e-mail
address for domain).  I want to open the database for download through me only
under the Attribution-NonCommercial-ShareAlike 1.0 license (I wish 2.0 would
get out already).  What I want is for the website itself to be completely
restricted, but they can download the database through me under the above
license (I ddon't want them running a harvester bot or anything).  Does anyone
see any problems with using the above license on this kind of site?
