I just wanted to tell you that the next nightly build (Sept 5) will be the first build that includes TLS and SASL support for c2s. The code is working very well and has been tested with many clients. Thanks to Hao Chen.
As you can see this thread was marked as a question so there are some points waiting for you if you report errors regarding these new features. We will soon release a JM 2.3.0 alpha version.
