Perhaps you're looking for PathPrefix (coming to a new Catalyst near you 
... eventually -- it's in svn now.). For now, do this:

sub _parse_PathPrefix_attr {
     my ( $self, $c, $name, $value ) = @_;
     return PathPart => $self->path_prefix;
}

sub get_id : Chained('/') PathPrefix CaptureArgs(1) { }

You can put the "_parse_PathPrefix_attr" sub in a base controller and 
all of your controllers will have access to it.
