This definitely seems like we have the same goals. And the described
usage scenario is also similar to what drove me to write the
dispatcher library in the first place -- only the earlier motivation
was CIMD2 processing.

Now though I'm actually using it as a sort-of Front Controller for an
HTTP based service I'm working on -- where it holds implementations of
the handlers dispatched according to the resource being requested
through a URI.

The latest code can be gotten from SVN at Sourceforge:
