Custom Script and Gallery Modification

I have 3 servers running Gallery. I need to allow users to login from a central location no matter which server they are on. Script 1 - A copy will be placed on each Gallery server. The script will have variables for the MySQL connection, and will have a secret ket defined. It accepts external requests that specify a username and the secret key (not the user's password). It checks the secret key, then if the user exists on that server, it will return "Yes" and the registration date. If the user does not exist, it will return "No". Otherwise, it will return "error". Script 2 - This will be installed at the central login location (a fourth server). It will have the URL's of the 3 copies of the above script defined in an array. It will ask for a username and password, or accept those variables passed to it from an HTML form or from script 3. When it receives the user info, it will poll Script 1 on all 3 gallery servers to see if that username exists. It include the secret key but does not send the user's password. If one server responds that the user does exist, it will redirect the username and password to that gallery's login url as an http post. If multiple servers report that the user exists, it will display a page showing the multiple registration dates for that username on different servers, allow user to select which date they registered on (as a radio button selection), then redirect their login info to the correct server. This script will also process requests from script 3. Modification 3 - Just a modification of the gallery code which will be installed on all 3 Gallery servers. If someone signs up for a user account it will send a request to script 2 to see if the requested username exists anywhere else. If it does, it will create an error in the registration screen telling them to pick a new username.
