Morris & group, I think that I am missing something here: ECB is a component of LRW, so any system that uses LRW in particular also uses ECB.
Not knowing much about NIST certification, I assume that to be certified you need to demonstrate that (a) you are using a NIST-certified mode, and (b) you are using it according to whatever conditions are described in FIPS 140-2 Any system that uses LRW would meet (a) above, so I would have though that such system could get NIST certification if it demonstrated (b).
