I saw a really neat-looking block on a site the other day, and I was wondering if there is a module that replicates the functionality w/o the writer having to do a lot of work.

Is there a module that will:

1) Scan a node for links the author used within;
2) Go to the Web, grab the name of the Web site and the page title; and
3) Return the information in a block or CCK field.

I emailed the developer, and she implied the work had been done mainly by hand, but could be accomplished through a Link field. Anybody know of a module that could automate this? Searched for one, but couldn't find it.
