After chatting with Chris privately it turned out that the confusion within the Chat example is partly because I did not find a good and simple solution for mixing user input and chat output asynchronously in one terminal stream. One can possibly do better, here. 
Also, apparently I left some debug flags active in the library which does not help to explore it. Sorry. You can turn debugging mode off by setting all debug flags to False in DebugBase.hs. I will correct that with the next update as well.

As a quick fix to put the documentation online it can be downloaded from http://www-ps.informatik.uni-kiel.de/~frk/dstm.pdf, also available through my very rudimentary institute's web presence http://www.informatik.uni-kiel.de/prog/mitarbeiter/frank-kupke/.

>> Hi,
>> DSTM is an implementation of a robust distributed Software Transactional Memory (STM) library for Haskell. Many real-life applications are distributed by nature. Concurrent applications may profit from robustness added by re-implementation as distributed applications. DSTM extends the STM abstraction to distributed systems and presents an implementation efficient enough to be used in soft real-time applications. Further, the implemented library is robust in itself, offering the application developer a high abstraction level to realize robustness, hence, significantly simplifying this, in general, complex task.
>> The DSTM package consists of the DSTM library, a name server application, and three sample distributed programs using the library. Provided are a simple Dining Philosophers, a Chat, and a soft real-time Bomberman game application. Distributed communication is transparent to the application programmer. The application designer uses a very simple name server mechanism to set up the system. The DSTM library includes the management of unavailable process nodes and provides the application with abstract error information thus facilitating the implementation of robust distributed application programs.
