Tom Wickham-Jones' book "Mathematica Graphics" describes 
and uses a package (ExtendGraphics`LabelContour`) to do 
this (amongst many other things). The electronic supplement,
including this package, is available on MathSource,
Wolfram Research's electronic library of Mathematica

Here is the MathSource description:

0205-041: Mathematica Graphics: Techniques and Applications by
Tom Wickham-Jones, Electronic Supplement

Tom Wickham-Jones

Revision date: 941206 

These files form a set of extended graphics functionality 
and are used and described in the book "Mathematica Graphics: 
Techniques and Applications" by Tom Wickham-Jones, published 
by TELOS/Springer-Verlag 1994 ISBN 0-387-94047-2. They 
provide functions that include the plotting of surfaces and 
contours over random data sets, labelling of contour lines, 
plotting contours subject to a constraint, smoothing contours, 
plotting field lines, a collection of geometric functions in 
two and three dimensions, as well as the ubiquitous fractal 
plot. Some of the functions require MathLink binaries which 
are available in source code and are compiled for Macintosh 
and Windows computers.
