Ah, I see, we're talking about different things. I was talking about
adding categories and associate appenders with them. You're adding
them to the hierarchy and rely on category inheritance.

So you want a custom appender that dynamically changes the file it's
writing to. Since the appender's log() function gets 'log4p_category' in
its %param hash, this should be straight-forward to implement.
Sounds like an interesting idea, I'm looking forward to it!
