I've thought some more about writing a PAM module, but what's the 
solution for people who don't have pam and _must_ authenticate from 
/etc/passwd,shadow (getpwnam, getspnam)?

Seems to me the only truly universal solution is to do this inside 
dovecot. It already has code to mangle the username with modifiers for 
mailspool location, so applying the same code to allow modifying username 
would seem to be a logical and consistent extension of existing dovecot 
behavior.
