Mario,
Although client discovery is in code it has never been announced. It will
be dropped in the upcoming release and client mode will appear for ordinary
tcp disco.
As far as reconnection - you raised a very good question. It is currently
under development in new API and will be available soon.
For now please go on with TcpDiscoverySpi.
