Just fiddling around here:
 
C:\misc\PythonNet-1.0-beta3>python
Python 2.3.2 (#49, Oct  2 2003, 20:02:00) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import CLR
>>> L = CLR.System.Diagnostics.Process.GetProcesses()
>>> for x in L:
...     if x.ProcessName == u"python":
...          x.Kill()
C:\misc\PythonNet-1.0-beta3>
 
This is one of very many scary things that can be done very easily
using Python.Net.  (I haven't tried to see what happens if it attempts
to kill all the other processes before committing suicide...)
 
Too much rope?
 
Anyways, this is certainly a great way to fiddle around with the
Libraries.  thanks again.
