Perhaps one should consider Parylene as a coating and preservation
material. Parylene was demonstrated by the Getty some years ago at
one of the AIC meetings.  It formed a thin, invisible, pore-free
coating that could preserve things like feathers and brittle paper,
and impart them some strength for handling.

I believe that they showed a Parylene-coated butterfly wing, and the
coating was strong and invisible.  Reversibility was a problem...

On the other hand, maybe one could eventually replace the tobacco

Size of chambers for coating could also be a problem--usually
Parylene is used for small items.  There are a number of Web sites
about Parylene, and it is currently used for things like coating
medical devices and printed circuit boards for use in extreme
