I came across a couple more links of interesting information (if you haven't already discovered them):

Doom 9's forum: Recover image from shutterless 16mm projector capture
http://forum.doom9.org/showthread.php?p=1531961

"I have posted here before about the unique way that I capture film from a shutterless 24 fps 16mm projector."

"I remove the shutter from the projector; I then point an NTSC interlaced camcorder (it HAS to be NTSC, and it has to be able to capture interlaced video -- 60p would also probably work) at the projector and set the shutter speed to 1/1000 of a second. It turns out that doing this absolutely guarantees that the camera will capture two successive fields from each frame of film. The video camera and the projector are not synchronized, so as the capture proceeds, sometimes you get two good fields in a row, with the next field all blurred because the film is captured during the moment the projector is moving the film to the next frame (remember, the shutter has been removed)."

He includes samples of his raw-captured and post-processed efforts. Crisp. Clean. Impressive.

And I think he mentioned using the "reverse lens" trick for capturing from a projector. If not him, it still is a useful technique and described well here:
