Joomla XML-RPC Plugin

Basically I require an XML-RPC plugin for Joomla, that deals with mySMS and Community builder components. It will basically serve as the communication between Joomla and a mobile application. It should be able to do the following and have responses in XML - - Register as a user (using Community builder plugin) - Authenticate user details - Verify cellphone number (sub functions: request pin code to be sent to mobile, verify entered pin code) - Send SMS - Send bulk sms - Send to user group - Modify user groups (create, delete user group - Retrieve phonebook - Add user to phonebook - Retrieve sms history - Invite friends (i.e. bulk sms with predefined message) The script should be called for example - [login to view URL];user=username&password=password&to=mobilenumber Only those experienced with Joomla programming please.
