Well, I have started with some practical stuff rather than estimations. Overall everything seemed too complex when reading FaceBook docs, so I decided to split this plugin into several small parts, each can be developed and paid separately.
The first part I'm currently debugging is called directly "FBConnect". It provides very basic functionality which is
- Letting people quick register with their existing FaceBook accounts
- Letting users quick log in with their FaceBook accounts
- Letting existing users attach their FB accounts to their Cotonti profile
- Providing basic objects and connection for other plugins to utilize FaceBook in Cotonti
I will also probably integrate a notification/invitation into this plugin or make it a separate plugin.
What can be done after this basic FBConnect functionality is available? Here are some examples:
- Use "social widgets" almost without any coding at all, just with XFBML in your templates.
- FaceBook Profile plugin to display FB profile details on your site and publish stories from your site to user profile
- FaceBook Friends plugin to make FB friends also friends on your site and provide some social interaction
- FaceBook Social Comments plugin (normally is done via XFBML but could be extended for better integration)
- FaceBook Profile Boxes plugin to post content on FB profile boxes
- FaceBook Publisher plugin for more sophisticated content publishing in user stream
- FaceBook Pages plugin: make an automated FaceBook page for your site
- FaceBook Gallery, FaceBook Sharing, whatsoever
