Please excuse this bit of self-promotion, but the
project a small group of us at NTT are working on
is related to this. We are looking at ways to
automatically form links (not HTML links per se,
but links none-the-less) for the purpose of efficient
searching and improved browsing. We hope to have
an alpha-version out for medium-scale experimentation
around September, and will be looking for people to
volunteer computer resources to run servers.
