Nice to hear that transition will be easy. Unfortunately I'm already using 
Numeric 24.0. I wrote a small example using wxPython which works with Numeric 
but doesn't with scipy.base:

import wx
from wx.lib import plot

from scipy.base import *
#from Numeric import *

class MyApp(wx.App):
     def OnInit(self):
         frame = plot.TestFrame(None, -1, "PlotCanvas")
         gr = plot.PlotGraphics([plot.PolyLine(transpose([arange(10),arange(10)]))])
         return True

app = MyApp(0)
