Key size

The article currently has "In the submission of proposals to the U.S. government, IBM proposed a 64-bit key". Can we document that? Other references I've seen, including one I've just added to the article and Applied Cryptography p 267, all give Lucifer key size as 128 bits. This does not necessarily mean the quoted assertion is wrong, but it does raise questions. Sandy Harris 02:33, 3 November 2008 (UTC)
