A plugin for reports which are currently not supported by existing hudson
plugins would be very helpful.

Let me explain: Let's assume there is a new report or metric which can be used
in an ant, maven or whatever task, a plugin for hudson is not existing and
nobody wants to write it.

In this case a "generic report plugin" would be very helpful to display a link
to the generated report in the project view, like "Document" for the generated
Javadoc.

It could be very similar to the Javadoc generation, but the configuration entry
should be expandable to support more than one sort of report, with the ability
to give some meta information about it in the project view and links to the
particular index pages.
