The following just came to my attention. van Benthem has a paper on logical pluralism out in AJL. The paper is called Logical pluralism meets logical dynamics? and is accompanied by a paper by Graham Priest, Logical Pluralism Hollandaise. van Benthem's paper, I believe, is a written version of his pluralism talk at the Tartu conference.
The following is the last passage---entitled Logical Pluralism---from an earlier van Benthem paper, The Landscape of Deduction:
In other words then, the secret of reasoning need not be hidden in any particular treasure chest, hidden somewhere in the above landscape, waiting for us to come with daggers and spades, in order to fight about preferences and priorities: the true marvel might well be that landscape itself. (ibid., p. 374)
