Hi Maarten,

Logback supports variable substitution through various means. See 
the section entitled Variable substitution in chapter 3 of the manual [1].

There is the substitutionProperty tag which can be used to set single
properties or from a file or a resource.

However, I think that you need a more dynamic behavior. In logback 0.9.9
properties are set per logging context. (Previously they could be also set per
Joran  instance via a InterpretationConext).

So, nothing prevents you from setting the properties for the context. For
example the following code should do it:

LoggingContext lc = (LoggingContext) LoggerFactory.getILoggerFactory();
context.setProperty("filename", "c:\myfile.log");
JoranConfigurator jc = new JoranConfigurator();

Does it makes sense? Would the above work for you?
