This is an interesting idea that could probably not be too hard to implement in
Java using a read only random access file.  Basically, a stream based parser would
dump the contents of a very large document directly into some DOM format for a
random access file.  You would then have a special DOM implementation that is an
interface to this file.

Nevertheless, this sort of stuff would probably best be handled by some
comprehensive database which presents a DOM interface to the DOM data.  I think
this is probably what companies like Oracle and IBM may be up to, but who really
knows.  If you wanted to go to the extreme you could even represent an entire
directory service like NDS this way.
