This is not entirely related to your request, but knowing that you don't want to use the command line tools really made me interested about your project.

Do you have any intention to release an API that uses the DCE/RPC commands that are available in the Active Perl Win32::NetAdmin module? I'm very interested about that but I lack the knowlegde to create the necessary glue using XS and the C libraries from Samba team (libmsrpc.h).

I'm asking that because I'm not using Samba with LDAP support, but still using the smbpasswd (and in the future the tdbsam). Nowadays I'm suffering from having to edit the smbpasswd mannually, since Samba doesn't honor the lock created by my Perl application (see flock()). Using DCE/RPC would solve this but I'm not running the application from a Windows box (actually is a Linux one).

Now related to your question... I don't think so I'm the correct person to tell about that but I think using CPAN features (and probably manually creating a mailing list) is a better option. You could use a Sourceforge's account for the project too.
