As noted in the discussion of module interconnection formalisms, we have
developed a small number of software configuration mechanisms. DIFConfig is a
primary example of such a mechanism that supports the development of
hypertext-based application environments that can integrate large-grain
software components. Our experience with DIFConfig has been very promising to
date. However, the current DIFConfig implementation, based on the original DIF
hypertext backplane, lacks capabilities we now consider desirable. Thus, we are
currently directing effort to extending DIFConfig to support the DHT service
layer, as well as to incorporate other software reuse mechanisms described in
this section.
