That this discussion is happening NOW really surprises me.  I have
been following this list for a couple of years now, with the intention
of eventually using numerical Python as the main teaching toolbox for
numerical analysis, and possibly for the migration small research
codes as well.

The possibility of doing numerics in Phython has always intrigued me.
Right now I am primarily using Matlab.  It's very powerful, but not
free and the language is horrible; Octave is trying to play catch up
but has mostly lost steam.  So a good scientific Phython environment
(of any sort) would be a really cool thing to have.

However, two things have always held me back (apart from coding small
examples on a few occasions):

1. Numerical Phython has been in a limbo for too long (I had even
   assumed a few times that both Numeric and Numarray were dead for
   all practical purposes).  If there are two incompatible version for
   years and no clear indication where the whole thing is going, I am
   very hesitant to invest any time into writing substantial code, or
   recommend it for class room use.

2. Plotting is a major issue.  There are a couple of semi-functional
   packages, but neither a comprehensive solution nor a clear
   direction for the plotting architecture.

Short, I see a lot of potential, unused mainly because the numerical
Python community seems to lack clear direction and leadership.  This
is a real showstopper for someone who is primarily interested in
building on top.

I am still hopeful that something will come of all this - any progress
will be very much appreciated.

Best regards,
Marcel
