An interesting idea, but this still doesn't take into account the
development that might happen if a group was _completely_ isolated
from the rest of the world--such as native Australian languages.  As
the group invents new technologies, they still might change their
language somewhat.  However, this is still interesting.

Warning: here be gmail.  Arrr!
