Also, let me add as well that ccHost can also do full dumps of all
hosted media to ATOM 1.0, RSS 2.0 and other feed formats in the future.

One can generate these feeds with the script on one's system:

    php PATH_TO_CCHOST/bin/data_dump.php [OPTIONS GO HERE]

Here is one cronjob for generating an atom feed every 3 days:

15 4 * * 3,6 cd /web/ccmixter/www && /usr/local/apache220/php/bin/php
> bin/data_dump.php -o atom.xml -t audio -f atom 2>&1 >/dev/null

The downside to using this data is that it is not a realtime selection
of content, but worthy for those who might have a search engine or some
system that crawls sites.

Also, IMO, it is best to use the ATOM feed if you go this route
primarily because of the good political situation around it.
