Dumdum I looked into this before. Its certainly interesting. However, DW is likely more simple, and as is widely recognised, already extremely secure (if one can't brute force a strong diceware password for 100's of centuries anyway, why go to the extra effort for a couple more centuries, for example). DW will be broken way before that, as will likely any other methods we currently employ as technology advances. In my opinion, The best thing to do is to keep it as simple whilst as secure as one can - whilst keeping abreast of what's going on in the field and adjusting accordingly.
