It was just a joke... fyi, I'm an ex-IBM'er, and it amuses me greatly
to see the "we can do anything, and if we can't, it's not possible"
mentality still in action.
No, I don't think that maintaining hypertext links within large
collections of texts is currently easy and quote-unquote affordable,
and I don't have any magic tools, but that has nothing to do with
whether or not such a task is "impossible". Limitations of current
technology should not be extrapolated to judge possibility or
impossibility; I would have thought the Wright brothers taught us that
principle some time ago.
Pardon, however, the humor,
