I am not sure about performance ramifications, but couldn't this be achieved by having some code that could add appenders at runtime with both an MDC filter checking, say, "username", etc coupled with a secondary filter that could filter based on a LoggingEvent's level? Essentially, the base configuration would enable debug for all but have default filters that disallow appending less than ERROR? When specific users log on, special appenders could be added at runtime whose filters would allow only that/those particular MDC value(s) but would essentially circumvent the default level filter and allow, say debug messages.
