Thanks. As Toby and Zach pointed out, there are certainly multiple was to address this. I won't bother explaining a use-case for this kind of meta-data, as it's easy enough to add these in application- specific manner without modifying hunchentoot.

extend the dispatch table to provide metadata for each dispatcher
Quick way: you can use the documentation strings of the dispatchers to hold arbitrary metadata. You can usually put all kinds of stuff in a 'documentation string', in spite of its name, and get away with it.

But! "Conforming programs should not depend for their correct behavior on the presence of those documentation strings. An implementation is permitted to discard documentation strings at any time..."
So here's a standards-compliant way: put all your metadata into a global hash-table indexed on the dispatchers themselves.
In either case I suggest writing your own create-...-dispatcher helper functions to populate the metadata.
