I'm not sure what kind of integration you mean. JFBConnect creates standard Joomla users which any component would see as any other user. Additionally, the FB Like buttons and Comment box (as well as any other FB widgets) can easily be added to EasyBlog pages with either a module or using our easy tags (ex: {JFBCLike} ) in the template or blog articles themselves.
Hope that helps, but if there was something specific you were looking for, just let me know.
Thanks,
Alex
