Mailing frozen worms

Regarding my earlier query about getting worms past the border patrol,
Leon Avery helpfully suggested:

>I used to just enclose them in an envelope and write "biological
>samples, harmless, no commercial value" on the customs slip.  

Now I have another question.  Is it possible to mail worms in a frozen
state?  Is dry ice cold enough to keep them intact for overnight
delivery?  Has anyone tried this, or must one use a vat of liquid
nitrogen in the back of a U-Haul like they did when the CGC moved to
Minnesota (obviously not too useful for getting worms from England)?
Thanks in advance.
