But really, I'm not going to be using My::Hash::Tie::Class. I'll be working with Apache::Session or Apache::SessionX. (That was meant to be a metasyntactic class name variable.)

Ah. In that case something like this will probably do the trick (untested code):

package Tie::WrapUsing;

sub TIEHASH {
    my ($class, $object) = @_;
    return $object;
};


package main;
use Test::More tests => 2;
use Apache::Session::File;

my $object = tie my %orig, 'Apache::Session::File', undef, 
    { Directory => '/tmp' };

tie my %dupe, 'Tie::WrapUsing', $object;
        
$orig{foo}=42;
$dupe{bar}=24;

is $dupe{foo}, 42, 'change in original reflected in duplicate';
is $orig{bar}, 24, 'change in duplicate reflected in original';

However, your real problem seems to be that you want to use a tied hash as an object - which kind of defeats the purpose :-) If I were you I'd use an object-based session system like Cache::Cache instead.
