For the sort of 'new' camera that is included, I would exclude anything auto-focus. The 'point' of this sort of camera is to be in control of viewing and focussing, independently of automation (though an electronic ranging system would be ok) and the lens fitted - that would include manual scale-focus cameras with a viewfinder perhaps, oops. If not, then every autofocus point-and-shoot should be included as they are small, don't (always) have TTL viewing and often have a viewfinder of some sort. The likes of the X100 are not rangefinder cameras, unless a submarine is a fish.
Regarding distribution, for practicalities a PDF would continue to be optimal I suppose. Are there online print-on-demand publishers who can take a PDF file as input, assuming the page-size etcetera are carefully chosen? That might provide a paper option for those who want it, though the price per copy would be higher of course.
