I know it's possible to dig into someone else's lexical scope, but it's far more difficult than doing $obj->{foo}. Ultimately, I can't do anything to stop someone from tralling through /dev/mem or the equivilent on another system.

You don't have to go as far as that in this particular instance. All you need do is fake being in the appropriate package, which isn't hard ;-)

As you point out, this isn't really the issue - the issue is accidental interference rather than deliberate trespass.
