Sort of, yes. The problem with Wiki's is that they can be a little unruly. But for an entirely electronic environment, that would work well. You can run mini web servlers and even mini-DBs on a PDA, but I don't know how well a wiki would run from there. Thus, a static doc organized into sections and chapters and such may prove more useful. Plus, if done correctly, could even be printed.

I know of several Linux doc projects that have gone to the printers and you are basically paying for the media. So, maybe after a certain point, ETS could get it printed and take some profit from the book sales? I don't think that's precluded in most of the licensing schemes....
