For those that have some down time over the holidays (and I recommend all should take time to 'sharpen the saw') and feel like a hell of a yarn (with tons of crypto references), allow me to point you in the direction of Cryptonomicon, by Neal Stephenson.
Bruce Schneier (diligent Wavoids would know that name) even develops a crytosystem based on a deck of cards for the book. A workable, albeit somewhat confusing to my middle-aged, old dog not looking for new tricks brain, crytosystem.
And if you've never read Stephenson before, it's fast (even though it's 900+ pages) and dryly funny.
Happy New Year all...
