Ah, ok.  I think it's possible, too.  There are left-margin and
right-margin text properties.

,----[ (info "(elisp)Format Properties") ]

| ‘right-margin’
|      This property specifies an extra right margin for filling this part

So possibly adding these properties to some paragraphs in your buffer +
`visual-line-mode' might do the trick.
