SSNs and VA

FCW describes a bill to force the VA to stop using SSN's.  On this weekend I want to pat myself on my back--the SCIMs data design was intended to allow FSA to stop using them, and that was 20 years ago.  I hasten to add that I've no information or confidence that all FSA systems no longer use SSN's, or even that SCIMS doesn't.  The force of inertia and the interweaving of dependencies hard to overcome.
