"Never" is one of those words…

There is no technical reason that prevents Facebook providing S2S.
Even with their usage of your own email address as login.

When you add a new buddy to your Facebook chat app, say
melo at simplicidade.org, they could offer the option of using my
Facebook IM account (melopt at facebook.com, who they know is associated
with that email address) or a remote Jabber/Gtalk/XMPP account.

The person identifier you use to add a buddy needs not be the actual
XMPP JID you'll use to communicate. It's just a mapping process at the
moment you add the buddy account.

Only political/strategy reasons, and possibly a little concern with
another attack vector, prevent Facebook from adding S2S.
