Which of course explains why most software does *not* include this 
feature. :)

The only similar thing I've seen in commercial software is in Mac OS X's 
"Console" application, which is used for viewing log files.  It has a 
"Filter" field that's used to display lines matching a string, and it 
updates its display as you type.  If Emacs had this, I guess we'd call 
it "Incremental-Occur".
