We are a Boston-based non-profit startup. We are creating a social networking site that connects various university students to art and volunteer opportunities in their area. The social-network is based off the very well coded JomSocial component for Joomla. JomSocial already supports limited migration for Facebook users via the FacebookConnect API, and also supports OpenID. We would like to create a more complete option based on RPX ([login to view URL]). The fields we want to sync with RPX are name, email address, gender, birthday, timezone, website, phone number, profile picture, address, current status, interests, and friends. For someone familiar with JomSocial this would be a very quick project. As we are a startup with zero funding I will be paying this out of pocket, and because of the small budget I wouldn't expect this code to be proprietary to our company. In fact, the need for something like this is very big in the JomSocial community; I believe you could sell this in their extensions directory and make a decent penny.
I know exactly what you want and this can be be done very quickly . I am expert with joomla and JomSocial Sites. Also you can have examples if you request.
