I am currently using php melody and I want to integrate wordpress so my php melody users can fully use the capabilities of wordpress. If I install buddypress I want my php melody users to be able to use those functions, if I install an ecommerce plugin to sell products on the blog then I want my users to be able to use those functions. If you think you can accomplish a COMPLETE BRIDGE for PHP Melody and Wordpress then please bid. I look forward to hearing from you if you think you can accomplish this.
I prefer this to be a plugin.
