Jess, you can use Chainsaw to connect to applications using log4j1.2,  
seriously.  I do it all the time.  The _only_ thing that I appear to  
miss is that log4j1.2 binary serialization of LoggingEvents does not  
currently ship all the MDC value, so while the event appears fine  
inside Chainsaw, if you have juicy MDC values on an event, the MDC  
bits just don't appear.  This is, to me, a feature I think log4j1.2  
is a must have because, really, IMHO, Context is what enterprise  
logging is all about ("No Log Line is an Island").

Now, the argument that Chainsaw is built on top of an alpha release  
is still sort of valid, but I think that's really a 'hidden' problem  
of Chainsaw, rather than anything that is restricting a user.  To the  
end user, they really shouldn't care as long as it works.
