Things to do to get a better world
==================================

Libraries:  don't restrict the module to libmhash, use 
libcrypto from OpenSSL project or
libgcrypt from GNU project.

In case of non existant virtual host (aka no directory), be able to 
redirect to a default web page.

Then build a shared cache to store stat() results to fasten the process.

Verify the environnement variables and logs to be sure
it support virtualhost like Apache virtual host.

Patch Apache to support dynamic document_root: having a document_root
per request will really help to have hash virtual host behave like
traditionnal virtual host (with no need to export exotic environment
variables). This would also help the plain old mod_vhost_alias which 
have the same limitation.

Support the same useful option than mod_vhost_alias.

Rewrote mod_rewrite (See you in next episode).
