Same suggestion as always, add limited support for social login
I would suggest to make 2 versions of the module, the current free one, and another paid one with limited social login support, basic account creation and logni for everything (Fb, TW, G+, Lin) and then if you want the extra goodies (ograph, integration with community streams, details import...) pick JFBConnect/LinkedIN Connect
Not all sites do require all JFBC has to offer, and they could go with some more basic module (as they do already, sociallogin, axaj login®ister...) you could have a cheap module that does same, that would make people "used" to using SCLogin
