Automatic Mass Form submission panel

basically I need an automatic mass submission panel to automatically post data to forms such as [login to view URL] and alot of similiar sites. Some sites require a login before submit, some do not, all have different variables etc. Some key features to include: -should be coded and managed via PHP/MYSQL -easy to add/remove My domains to post for -easy to add/remove sites and their required variables for submission -read the RSS feeds for my hosted content, to easyily import into the submission process for each of my sites. -auto pilot or scheduled submissions(be able to set tomorrows items to post and through out the week/month etc... or let it automatically choose latest feed from rss to post each day. or somthin to that extent -output log after mass submission(to show sucussful/failed posts) please remember this is just a general idea, i would love to hear your input about this and what else we could add to make this better and more simple yet productive. Thanks
