chromatic's ideas sound pretty solid.
The inheritance part should be pretty easy also. Just modify the @ISA array. Maybe write a generic plugin module to provide common routines. Then force the plugins to inherit from the plugin module. So in a different plugin type module do: 
use plugin;
push(@ISA, "plugin");

That way routines will be looked for first in the local package then they will be looked for in the packages named in @ISA. The plugin package might provide routines to set the subroutine references etc.
