Reading back through this thread, it seems to me that the issue at hand is not whether Mark's work has been reviewed but rather Tony's concerns regarding the accuracy of the various documents and hence whether Mark is evading debate or same.
Let's stick at Peer Review for a second. What do we really mean?
Generally speaking, "peer review" refers to the process used by publishers and editors of learned and academic journals to provide a chance for scholars in the same field to examine and critique a paper or book before it is published, to help ensure its integrity and veracity. It is, if you will, a more formal (and some would say adversarial) version of asking a colleague "what do you think of this?".
Now, as a number of others have pointed out, Mark's work is not a theory or scientific hypothesis. Rather he collates various strands of research and (depending on your viewpoint) seeks to either hold up the innacuracies to the light of day or alternatively misrepresents the sources in an attempt to ridicule them.
The parallel is not the scientific process of peer review, but rather a more journalistic model. One might draw a parallel to the work of investigative journalists (for example Pilger) or even, I suppose, Michael Moore.
I doubt if there is a single person here at JREF who whould object to more responsible, accurate and unbiased standards of journalism and debate concerning the events of 911 or indeed generally. If you have concerns, then you have a right to air them.
However these concerns have to be based on issues of accuracy. If you feel that Mark has misinterpreted or misrepresented evidence, then the solution is not "peer review" but rather for you to collate and present these errors in the same manner as Mark did. Let's have trackable sources. Let's have the accuracy and reliability of such sources assessed by the author. Mark cites his sources, and they can be readily checked by someone with the time (and patience).
The issue of the format for such a process is, I think secondary. It is certainly not a process which lends itself to the rapid fire we sometimes see here. Each party will want to go away and review the evidence before responding to individual points. We will also need a way of ensuring that the discussion remains on-topic and does not seek to avoid difficult issues.
A moderated thread seems an excellent idea to me, with all other authors - myself included - excluded and a gentleman's agreement that no-one will start huffing and puffing if a reply doesn't arrive by return. Whether the goalposts have really been moving recently or whether you have both simply mis-read the posts is incidental. Lets start a fresh sheet of paper, and let's start it now.
Are the two of you ready, willing, and able to do so?
