While it isn't there now I don't see any reason it couldn't be added. I've
implemented a couple of standalone servers but not integrated with the
configuration. It would require a change to BaseConfiguration and we would
need a Receiver interface - is there one?  I'm pretty sure they would need
to use Managers just as the Appenders to so that they can survive a
reconfiguration.

I haven't programmed multicast recently but my recollection was that it
isn't too different.  I don't see why it couldn't be supported.

There is still a lot of work to do. I've not implemented a DB Appender, JMX
support, OSGi support but I believe the foundation is there for them.
 Logback supports XML and Groovy as configuration mechanisms. Currently,
Log4j 2 currently supports XML and JSON. I've not convinced myself why
using a DSL is a good thing but it should be easy to add if desired.
