I'm sure most people on this list have heard of or use snort. There is an
add-on package called snortsam. This package allows automation of blocking
traffic deemed malicious via a null route statement or ACL statement. We
have been in the process over the last month of implementing this on our
network with much success. I think the only problem that we have had with it
thus far is underestimating just how well it was actually going to work. As
with any snort implementation, it takes time to tweak and tune the rule
sets, however we have managed to kill a huge amount of traffic either coming
from our customers or destined to our customers. While this is not a perfect
system, it is much better than idly sitting there and letting the abuse
continue.

Is this the kind of thing that could get a boost from projects like 
ThreatNet (http://www.ali.as/threatnet/)?

I've been peripherally involved with the project, mostly in chasing 
conceptual issues and hammering out the trust relationship details, in 
addition to being an rabid, er, avid developer of network management 
tools, right down to near-real time log analyzers. I think that if you're 
to a point that you trust your tools enough to make an informed decision 
and automate your null routes, why not expand on that and use the same 
networked intelligence the C&C's embody?
