In addition to the article on the Mark VII which I posted the link to, one can read the full text of a De Christoforo review of the relaunched Mark V here:

The article starts on page 108. One of the photos appears to show a drum sander being used as a thickness sander with the work off the table and possibly being supported on just the way tubes (not recommended!). CORRECTION: the board is on the edge of the main table (I still would not recommend it).

Why would you not recommend it? I have used that configuration quite successfully. Don't try to dimension with it; do LIGHT sanding only.

Good question. I haven't tried it and, upon reflection, I can't think of a reason -- as long as only very light pressure is used.
My original comment was based on my misinterpretation of the photo, which appeared (to me) to show the stock resting only on the way tubes. In that configuration my concern was that as the trailing edge of the stock came off of one of the way tubes that end of the stock could suddenly drop and the drum might launch the work piece.

Just like many other operations that can be performed while using the Mark V, stuff can happen. Take it from me, when surface sanding in this manner, the piece being sanded can get launched like a rocket. Too much pressure coupled with lack of control over the work piece and it is gone (about twenty feet in mt case). Fortunately, I was alone in the shop and I had the Mark V in a position where it launched out the door. It could have been a lot worse.
I learned my lesson and now I am able to use that method without incident. Just sand very lightly and make sure you can control the work piece. No small parts - finger grip is inadequate.
