55073 PHP expert to design plugin

We are looking for someone with an expert knowlege of PHP scripting to develop a plugin for an existing membership program. The software is called aMember. [login to view URL] Currently, aMember can only protect content on the same server as the aMember insatllation. The new plugin script must allow protection of directories on a separate server. The preferred protection method would use mod_rewrite. ServerA: Hosts aMember script & database ServerB: Hosts other sites that need protection The plugin should allow the protection to be enabled/disabled through the aMember admin interface. Must validate visitors to sites on ServerB against the membership database stored on ServerA, preferably with mod_rewrite protection. The key is that we want the plugin to provide strong integration between the two, not just a simple membership hack. We can set up sample installations for those that have strong skills and can first provide a detailed outline of thier ideas for a solid solution.
