hachoir-http is an HTTP + Ajax user interface based on hachoir-parser to explore a binary file.
This web interface for hachoir is in a beta beta version. It uses basic AJAX and a session manager, but must rebuild the parser every page load due to an inability to pickle parsers.
Idea: rewrite it with Python internal HTTP server?
