I downloaded and installed this new plugin on my Buddypress enabled site, http://www.extrafriends.co.uk.
Configuration was going well until the 'extended settings' tab in the Facebook setup when it returned a blank rectangular box after the usual facebook authorisation popup. At that point nothing happened so I carried on regardless with the remaining tabs.
Unfortunately it then began to crash my site so I had to remove it. This was only possible by renaming the plugins folder and then accessing the page through the dashboard as it was logging me out as network administrator.
I did notice however that the latest version listed is 1.0 BETA 2 but the download ZIP file contained 1.0 BETA 1?
