This is exactly the kind of thing which is wonderful at the SBL--a lunch conversation with a scholar, in this case Margaret Barker (although not at the SBL). Margaret Barker is an independent biblical scholar. In July 2008 Margaret Barker was awarded a DD by the Archbishop of Canterbury ‘in recognition of her work on the Jerusalem Temple and the origins of Christian Liturgy, which has made a significantly new contribution to our understanding of the New Testament and opened up important fields for research.’
Here's a link to other interviews with Margaret Barker thanks to Bill Hamblin. Also on this link are announcements of planned meetings of the Temple Studies Group the first of which is Melchizedek in Scripture, Liturgy and Tradition, to be held on Saturday 8 November 2008, 10am-4pm, in Oxford. Speakers so far are Crispin Fletcher Louis, Robert Hayward, Laurence Hemming, Margaret Barker.
