Love it!!!  I think we're ready for this now.

In this above example, the ignore list would only apply to the system list,
but not ignore tokens in the user list?  If an ignore list has a lower
priority number than all others, then words will first be ignored before
looking them up in any of the regular wordlists?

Will we rely on filesystem permissions, or build in seperate permissions for
updating system wordlists?  I suppose a group could be created for the
purpose of allowing only select people to register certain lists.  I assume
registration flags won't apply to ignore lists?

How about this:
wordlist=whitelist, ~/ignorelist.db, 5, I
wordlist=global_zoology_whitelist,
http://blah.org/bogofilter/ignorelists/zoology.db, 6, I
wordlist=primary, ~/wordlist.db, 7, R
wordlist=system, /var/spool/bogofilter/wordlist.db, 8, R
wordlist=zoology_spamtrap,
http://blah.org/bogofilter/wordlists/spamtraps/zoology.db, 9, R
wordlist=general_spamtrap,
http://blah.org/bogofilter/wordlists/spamtraps/general.db, 9, R

Where, obviously, people could maintain wordlists and ignorelists for select
groups of people with similar kinds of email.  The above likely belonging to
a zoologist.  Being able to retrieve wordlists from remote sites (perhaps
cached once a day locally, or else searched one token at a time remotely via
some server-side code) I think would be a huge advantage.
