We would like to integrate our online book-store with EditionGuard services as described in http://www.editionguard.com/ for Adobe book protection.
Our site is hosted currently on a windows 2003 server running Xampplite
with php and mysql. Wordpress 3.3.1 is used with the WP e-commerce
plug in and some modifications done by us.
EditionGuard has API documentation and they provide help, support and a trial account for 30 days.
