Right there, that would probably remove 80% or more of the vulnerable systems from the target space. Having 80% less compromised computers would be a VERY good thing!
I think my ISP actually has a good solution here. They ship ADSL routers 
where the default setup is using NAT, no DMZ, no port-forwarding. One 
easy call or email to support will get you instructions on how to switch 
to bridge mode on the box. This makees the average home-user invisible 
to the outside, while saving the ISP on cpu-time. They could do the same 
for outgoing port 25 also with an easy opt-out and I would not complain.
