[Poll for Mark Knowles] Explanation for Voynich text?

[nablator]

Cipher is maybe too restrictive, I took it in the more general meaning of any type of encryption.

Can you elaborate what you mean by that? What in your opinion do you think the options should have been?

There should be an option for ciphers that are more advanced than mono- or poly-alphabetic substitution: they are in a completely different class and some of them might even be possible: with homophones, nulls or vord-segmentation (in 3 parts or more). Then there are codes and algorithms (not necessarily as difficult to use as a mathematical algorithm or cumbersome as cipher wheels or a code book). My own favorite anti-polybius is difficult to categorize: it is an algorithm but it can work as a simple substitution for one-letter vords and also as a code generator.
