You probably want to use a compound path (one object for the entire
plot). See the tutorial at
http://matplotlib.sourceforge.net/users/path_tutorial.html, in
particular the compound path for the histogram example near the end,
and let me know if you have any questions.

Personally, I am more a fan of Ray's version, although Tom's version
would integrate more nicely with the current mpl codebase. There are
some nice features with Ray's version such as allowing to choose
density in both x and y directions.
I guess the major question is which style do we like better? Maybe we
could use both of these code bases to come up with a nice, generalized
version?

Ben, John: Later this week or next, I'll take a crack at adding both of
these to quiver.py and axes.py (one under the name "streamlines", the
other as "streamplot").
