We've had a similar library installed and enabled by default in the  
Aquamacs distribution for about a year now (see URL below).

Discussions with users resulted in binding <down> and <up> to the  
appropriate functions, but not C-p and C-n, so that wrapped lines can  
still be navigated comfortably.
If a mode binds up/down to something else than next/prior, this new  
binding is preserved.

IIRC, the functions `visual-line-up' and friends  that I wrote differ  
from the other available library in that they work well with variable- 
width fonts.

`kill-visual-line' and `kill-whole-visual-line', `beginning/end-of- 
visual-line' are provided as well and do the obvious.

Inevitably, some users were annoyed with the functionality, so it  
makes sense to allow for customization (e.g. with a minor mode  
`visual-line-navigation' or so).


Code:

site-lisp/macosx/osxkeys.el
(This library doesn't work as stand-alone, but I can easily extract  
the visual-line-* code.)
