The Legal Hypostasis of religious minorities in Greece

I was pleased to read Theodosis' post on this conference organised by PES: http://www.divshare.com/download/6390204-b62
Are any of you attending this event? I would love to hear your thoughts about it.
Apparently religious freedom (ανεξιθρησκεία) IS part of the Greek Constitution, as far as I know, but what exactly is aimed at the recognition of the legal hypostasis of minority churches?
Would love more info on this!
