Ed,
 A 'cleaner' approach.

The central (as opposed to key) point:
In the expression:
$hash{$ohk}->{$ihk}
$hash{$ohk} is the _value_ of a hash, but that _value_ is a reference to a
hash,
so we can use the '->' syntax. Think of:
$hash{$ohk}->
as identifying that (pesky anonymous) hash for us. Then the {$ihk} simply
identifies the value of that hash we want to print.
HTH

That is a good way to put things, I was hoping to move in this direction once i had a better idea of what the actual data was rather than dealing in delicacies ;-).

The good thing to know is once you *get* ref's you pretty much got'em, and you can move into just about anything after *getting* them.
