Illegal use of data
As the License and Site Access (http://www.imdb.com/help/show_article?conditions) will tell you, screen scraping is not allowed. Please do mention that on your freshmeat page.
"Robots and Screen Scraping: You may not use data mining, robots, screen scraping, or similar data gathering and extraction tools on this site, except with our express written consent as noted below."
Very easy to bypass
This "protection" is very easy to bypass with, for example, WWW::Mechanize::Sleepy (http://search.cpan.org/perldoc?WWW::Mechanize::Sleepy)
