Membership plug-in SAML 2.0 compliant

I have a client who is interested in having a corporate intranet site created.  Because they don't have a technology infrastructure that would allow me to run it behind a firewall and protect it from the outside world using that and VPN I am thinking I will use the membership plugin to control who has access to what sections/information in the website.  I do have a pretty clear understanding of this but they indicated they are seriously considering moving to a single sign-on (SSO) methodology and are looking at companies like Ping Identity to provide that SSO experience.  The qualification for integration into Ping (or the others for that matter) is SAML 2.0 compatibility.

That leads me to my question - can the membership plug-in be SAML 2.0 compliant?  How hard is that?  Can I do it?  Can I pay you to do it?

Thanks!
