technically it does not need a passwd, and you don't need to do password
sync.  i should work just fine.

it would be better to use group permission on the files and use your normal
user to edit.  www-data should only have write permissions to your logging
and upload areas anyway.  the web server should never be able to overwrite
your site code.  it would be even better to use SSH, still with group
permissions and your normal user.  most editors can edit over ssh "live"
these days, with the right plugin.
