globals() is actually local to the module.

#--file1.py--

globals()['numerix'] = 'numarray
import file2
#------------

#--file2.py--
print globals()['numerix']
#------------

$ python file2.py
Traceback (most recent call last):
   File "file1.py", line 2, in ?
     import file2
   File "/Users/kern/file2.py", line 1, in ?
     print globals()['numerix']
KeyError: 'numerix'

I think it's better to have an external setting which will work with all 
packages that have numerix capabilities (like matplotlib and scipy).
