There's the ServletTargetFactory that logs to the servlet container. It 
is declared in logkit.xconf and was used up to recently to log all 
errors to the engine's log.

About clustering, we have a component that I think won't work in 
clustered environment : the FragmentExtractor/Generator. It grabs on the 
fly parts of a document and keeps them in memory for servicing by 
requests that follow the current one. In a clustered environment, it is 
very likely that those requests are served by another computer in the 
cluster, and thus the extracted fragments won't be found.

As solution could be to store these fragments in the servlet session : 
clustered engines either use a single computer for a session or 
communicate session data between computers.
