I find myself also missing the man pages at times, but perhaps a web based one would be our best solution? In other words, make a seperate/add to the current FAQ information about each package. The maintainers/cross-compilers/programmers could be left with the responsibility of their own package.
I know what you will say, "But that's not really man", or "But that isn't on the fly", no it isn't. It is however, the most space conserving (for us, not Laze ), and simplest. If you crash your Z hard enough to be unable to access the web, you'll have to wait. This also leaves the possibility for each user to save the pages they need onto RAM or store it in whatever way they see fit.
