Matt,
Thanks for the info.  Great piece on AV as well.  I've used Sean Walkers
technique with some success on wide-field piggy back photos.   I can't
wait to employ yours.
Scott

Scott,

I'm not a hypered film expert, but...

Hypered Tech Pan apparently can keep in the freezer for years if
properly sealed.

Hypered color film can last about a month in the freezer if properly
sealed.

If you happen to have a vacuum chamber, hypered film can be stored in it
for a while.

For some reason, packing hypered film with desiccant and keeping it at
room temperature is not supposed to be as good as keeping it in the
freezer, but no one ever satisfactorily explained to me why that is the
case, because as I understand it, it is moisture that is the concern.
