My colleague and I have just finished an initial implementation of a new 
logging library.  We think we have some nice features that we hope may be of 
interest.

1)  Each logging statement is a standalone object (thread-safe initialised), 
which can be controlled independently.  Here are some of the consequences of 
this design choice:
        a)  You can control whether a log statement is on/off based on file, 
file & line, function name or any other indexing scheme you can come up with 
(e.g. "application component")
        b)  Each logging statement can have a separate list 
of "destinations".  These can be turned on and off at runtime.
        c)  We have lua bindings to the library, which is our primary way of 
controling the amount of output.
2)  A statement which is "off" is cheap (i.e. no streaming happens)  The main 
reason for this is that we want to be able to sprinkle a copious amount of log 
statements throughout our code and then turn them on/off should the need arise.
3)  Intuitive interface:
        LOG (<list of destinations>) << "blah";

If you find the feature set interesting, let us know and we can start filling 
in some more details.  We'd be willing to work on boostifying it should there 
be enough interest.
