Is Cameron ready to ban the 'European 17' (or whatever we should call it) from using EU buildings?

James Chapman, the Political Editor of the Daily Mail, has just tweeted the above. I'm hearing the same but only unofficially.
It's essential that Cameron does play hardball. France cannot be intransigent in negotiations and then expect to still use EU infrastructure... and by infrastructure I mean everything from EU paperclips to EU legal mechanisms.
It's not impossible that France may yet concede ground to Britain. We may then get an agreement of all member states but only if Cameron gets his safeguards.
