Yeah... but how else would the paragraph width be defined? Or do you
want the paragraphs to never break and only occupy one line? I
couldn't quite get it to work, but start with something like this:

Preamble:


\newlength{\parawidth}

\newcommand{\whitepara}[1]{
\settowidth{\parawidth}{#1}
\colorbox{white}{\parbox{\parawidth}{#1}}
}

In a paragraph object (minipage type label):

\whitepara{My paragraph \\ another paragraph}

It doesn't really work because \settowidth doesn't split stuff up into
paragraphs. If your latex-foo is strong then you may be able to write
code to split #1 into an array of paragraphs, call \settowidth on each
and select the maximum. I have no idea how though.
