That sounds fine, as long as it is clearly documented.

> Third, the /Custom/Path should really go away. We are all concerned that people can read security critical files from the whole file system. To read those files, people have to access to mhttpd, so they have to know at least the authentication credentials to pass the Apache firewall in front of mhttpd or

Yes, I agree that /Custom/Path should go away.
