Bush to Seek Cabinet-Level Domestic Security Office

What exactly does this mean? Will the Secretary of Homeland Security (if that's the title, and a stupid one it would be) have any more authority than the Director of Homeland Security? Or (as strikes me as more likely) will this have roughly the same impact as creating the Department of Veterans' Affairs did, and continue the diminution by expansion of the cabinet, which seems headed to becoming too large for every Secretary to fit in a room smaller than Madison Square Garden? Does being "Cabinet-Level" really mean anything anymore?
