Just to update people...  this has been in a holding pattern, because 
apparently there are revisions to SHA-3 coming down the pipe.  They want 
to address preimage resistance, and make things faster in hardware.

Random quote from NIST, on the NIST hash-forum, which doesn't provide 
detail but does summarize general feeling: "As best we can tell, 
continuing to pay that performance penalty for all future uses of SHA3 
has no benefit.  (All this is a longwinded way of saying: we were wrong, 
but hopefully we got better.)"
