This probably folds into the new features you have added for multiple
wordlists.  My point of confusion is the differentiation between $HOME and
$BOGOFILTER_DIR.

Using $HOME gives me the freedom to tune my wordlist to my email. 
Filespace hungry, but accurate.  Using $BOGOFILTER_DIR set's everyone to
one common wordlist/bogofilter.cf file.  Less filespace and less accuracy.
 But probably much simpler to manage for 100 users.

But the other question the comes up is: how do you execute bogofilter for
10 virtual users if none of them have a $HOME directory (because they have
no /etc/passwd entry) and no ~/.procmailrc file?

The only way I can imagine doing anything close to this is running
procmail from /etc/procmailrc and using the 'procmail -p' option to pass
in user information from postfix so that I can use the $USER to identify
their wordlist explicitly.
