You may want to consider also using the roman font for the non-math text

  from matplotlib.matlab import *
  plot([1,2,3])
  name = 'John'
  title(r"$\delta^{15}N\ \rm{and\ Trophic\ Level\ for\ %s\ Food\ Web}$"%name)
  show()


FYI: There are other spacing commands

  '\ '   : normal space, 30% of fontsize
  '\/'   : small space, 10% of fontsize   
  \hspace{frac} : user specified fraction of fontsize

See http://matplotlib.sourceforge.net/matplotlib.mathtext.html for
more info.

It doesn't work now (see link above).  It may be included in a future
version.  Wouldn't be too hard....  One problem with the approach
above is that mathtext doesn't currently use kerning data, so roman
strings like

  \rm{and \ Trophic \ Level \ for \ %s \ Food\ Web}

have nonideal interletter spacing.  Kerning is on the list of things
to do, which would make the solution above pretty good.  I agree that
allowing nested "some string $subexpr$" would be better.
