mechanism for specifying a cred checker for twistd plugins to use

Several plugins, such as words, ftp, mail, news, and conch, mainly exist to expose a protocol implementation to the world. These protocols all have the concept of a user and a session, which is implemented with twisted cred.
The twistd plugins in question exist to expose these protocols as useful tools to users without involving Python programming. However, in order to be truly useful, the plugins must be able to connect to an established user-database. Some ad-hoc work (conch's use of pwd, words' use of --passwd) has already been done in this direction, however, the authentication glue must be replicated (therefore replicated inconsistently) between twistd plugins. Currently they provide less than a pale shadow of the generality and utility of cred's implementation, even those simple checkers present in Twisted itself.
Checker pluggability should be easy to achieve with simple command-line libraries for each plugin to use, and a simple plugin system for checkers to register themselves.
