What MIME type is it using? I guess adding a variable like HTTP_POST_DATA
would be correct if it's not application/x-www-form-urlencoded. The other
alternative would be to make PHP "parse" the application-specific data like it
would parse the normal POST data and make a variable like HTTP_FDF_DATA.

HTTP_POST_DATA can be useful anyway, I have at least one application where it
would have made my life easier. My only worry is memory use for huge file
uploads and such.

In your module entry structure, there is room for startup/shutdown functions
for the module as well as each request. Example:

php3_module_entry xml_module_entry = {
    "XML", /* extension name */
    xml_functions, /* extension function list */
    php3_minit_xml, /* extension-wide startup function */
    php3_mshutdown_xml, /* extension-wide shutdown function */
    php3_rinit_xml, /* per-request startup function */
    php3_rshutdown_xml, /* per-request shutdown function */
    php3_info_xml, /* information function */
    STANDARD_MODULE_PROPERTIES
};

You can look at almost any extension for examples.
