The purpose of the mod.smalltalk project is to integrate Smalltalk with the Apache Web Server via Fast CGI.

On the page describing Fast CGI, they say:

FastCGI is a fast, open, and secure Web server interface that solves the performance problems inherent in CGI, without introducing the overhead and complexity of proprietary APIs (Application Programming Interfaces).

Apache also supports the XML Smalltalk project. XML/ST mentions SMIX, a new Smalltalk Interchange Format.

There's a good chance for confusion with SIXX, the 'other' Smalltalk interchange standard. But they are both the product of Masashi Umezawa 's three-man team. He explains that "SIXX is designed for serializing/deserializing object instances 'data'(states). If you would like to save/load Smalltalk class definitions, use SMIX, instead". SIXX is supported on most Smalltalk platforms and may be more mature than SMIX.
