Tunnel links?

Back in the 1990s there was a DOS program called IZE. Loved that program, but it didn't survive...

Anyway - they had a really unique form of hypertext: I call them tunnel links.

A tunnel link is one that goes both ways at the time of set up. You establish a link at a starting point, somewhere on Page A, and an icon appears, perhaps like this: >>

You then indicate where you want that link to go, much like a web based link with a hash mark, for example this: http://en.wikipedia.org/wiki/Hypertext#Early_Hypertext_Applications

As soon as you select your destination (somewhere on Page B), the system then sets up a return icon, perhaps like this: <<

Now - whenever you visit Page B, you have a link that takes you to Page A. Similarly, no matter how you arrive at Page A, you have a link available to Page B.

These tunnels then effectively become a precision hyper-cross-referencing system.

I don't know what it would take to develop such a thing, but if you don't ask...
