Study the 'Edit in place' possibility

We would like to know if it's possible to implement the edit in place on the fields that the user is allowed to modify.

Libraires we can check:

http://plugins.jquery.com/jinplace/

Also for tables:

On all element editable in place, a transparent border with an edit button is expected to display on :hover a visible border of the field to edit.
