Need to enable Registration -- will this conflict with Membership?

I have need of a plugin to allow LinkedIn users to auto-register on my site -- a plugin is available via Gigya, called Socialize WordPress. However, it requires that the WP site allow registrations, since it automatically registers a user when they first "login" with their LinkedIn account.

Now, aside from other issues it may/may not have, I'm just wondering what issues I'll face from Membership if I do turn ON the WP registrations. I'm hoping that there is a way to make this work, without hacking WP core files...

Any advice?
