Are you kidding? Facebook Connect might be OK for blog comments but for a professional site it is totally unacceptable. Since he's considering implementing SSO I would consider it a pretty serious project. You do realise many people don't have Facebook accounts, right? And not just because they haven't heard of it? Not one of my top 5 technically knowledgeable friends have a Facebook account.
