DNC.com has a good HTTP API that allows real-time scrubbing. You coule probably modify an AsteriskNOW installation (or similar) to call an AGI script prior to outbound dialing. The AGI script could invoke the VERY simple HTTP call and analyze the result. This would, of course, require a full national FTC Org ID/SAN to be useful for calling anywhere in the US.

It would need to be loaded with the national registry, as well as allow the end user to load numbers themselves. This could reside on a local server, or out in the cloud. Not quite a predictive dialer, since the end user will dial the number from the handset themselves, and receive an appropriate recording notifying them if the number dialed matched a "blocked" number.
