I really feel for you guys. As I've argued in another thread, I think SMTP
authentication will likely cut this stuff down to a trickle compared to the 
current
volume. As an ISP, how big a problem would you have with that. An even better 
question:
Would you have a problem implementing SPF, Caller ID and Domain Keys (i.e. all 
3)? It
gets to the same issue of changing practices for your users: at some point you 
have to
either bounce or segregate mail that doesn't authenticate.
