   This is available with vi under HP-UX 7.0 (and HP-UX 6.5 and before (??)).
   When set, 2 consecutive ESCs are required to exit from input mode.
   It's very useful when supporting the arrow keys and allows full/proper

   Do any other vi versions have this feature and/or is there a 'catch' ?

Sounds unnecessary: vi already disambiguates arrow keys from
user input by using timing information. For example, you can
type:

	:map! ^V^[OA ^V^[ka

to have the uparrow key function in insert mode.

Unless you have a very slow connection and are a very fast typist,
this should not present a problem.

I personally would hate it if I had to type <ESC> twice to get out
of insert mode.
