Will this module be published for others to use?  If so, can I suggest a 
feature?

One thing that's really important with logging, but rarely available, is 
not levels, but code areas.  I believe python, for example, allows you to 
name log sections:

    logger("mainsection.subsection.subsubsection1", "message1")
    logger("mainsection.subsection.subsubsection2", "message2")

and then you can enable, say, everything related to "subsection", but 
then filter out everything in "subsubsection2".

That's really important, when debugging/auditing complex apps, without 
actually wanting to modify the code just to find out what's going on.  
Especially since modifying the code can CHANGE what's going on.
