I don't know if this has any relevance, but don't the underlying
3Ware cards use a much bigger blocksize???  If this isn't an issue
from a compatibility standpoint, how about a performance one?

Or am I totally missing the mark here?

Are there any other limitations with using such small blocksizes? 
Even at 512bytes, we should be able to get 2TB (4Gblocks x 512
bytes), right?

Web site defacements are as much of a national security risk as
inner city kids spray painting.  There is nothing of value, and
nothing that can't be fixed with a little re-paint.  You'd have
to have the equivalent stupidity of someone parking an F-18 in
downtown LA.  Even then, the only damage would be a new scheme!
The US government wants life imprisonment for such "terrorism."
