And I really believe this is the simplest and exact solution:
Rugg (2004) claims that words might
have been generated using a ‘Cardan Grille’ – a
way to deterministically generate words from a table
of morphemes.
(Gordon Rugg. 2004. The mystery of the Voynich Manuscript. Scientific American Magazine.)
If you know there was a reasonably fast way to produce the content which has exactly observed properties, why searching for some more complicated explanation?
One wonders, when you consider things like this, if we ever have any hope of actually talking to a non-human intelligent species. Some human wrote this thing (and assuming they were not just pulling our leg, or as the XKCD comic guesses running some medieval D&D game) and we've tried for decades to figure it out. How could we possibly hope to even start on understanding a non-human document?
This interpretation is entirely possible, however there are two issues I have with that.
The first is that even in medieval times parchment wasn't cheap. It wasn't like anyone could get there hands on enough to make 200 pages of gibberish unless they were a relatively wealthy doodler.
The second is that were it in code, the sophistication of ciphers in the 1500's was hot high, and generally quite susceptible to the sort of forensic analysis that is covered in the ISI paper linked in the comments. As far as I am aware, the only cipher system, known at that time, that would not succumb would be a one time pad. And in the case of an OTP cipher it would reveal itself in other ways (lots of entropy in the words).
If it isn't clear, I do agree that it 'being in code' is the most likely reason it has not been deciphered, but that the cipher of that time is not breakable given what we know of 'plain text' of those times (the various languages it could have been written in) makes me wonder how we would fare against an alien communication (should we ever pick one up).

But consider:
> The first person said to have owned the manuscript was the Holy Roman Emperor Rudolf II, who reportedly was intrigued enough to buy it from its previous owner for six hundred ducats, around ninety thousand dollars in today’s money. (According to the manuscript’s radiocarbon dating, the book was already nearly two centuries old at the time of his purchase.)
Supposing it's random — perhaps the person who made it originally, two hundred years earlier, hoped to charge a similar price from either a gullible patron like Rudolf, or someone who hoped to find a greater fool like Rudolf?
Tis is very likely. I bought a map of the US for my dad (he collects old maps) which depicts California as an island some 10-15 years after they were sure it wasn't an island. It turns out that novelty maps were more in demand than real maps.
I just think its unlikely that an alien message would be coded. Our own messages sent with intent to space are not just unenciphered, they include a lot of meta data to make finding the patterns required to understand it easier.
If instead we used a one time pad, we wouldn't have much luck reaching out to aliens. This points to the more likely scenario that the manuscript isn't encoded at all (gibberish) or it was meant to be understood by only one person.
Does anyone have an analysis of the drawings? How accurate are they? What about the detail of the human anatomy, is it comprehensive? Is there any meaning in the series of diagrams?
These questions won't decode the text, but they may give an indication of the quality of the text.
Based on a WAG, I'd say the book's text is not particularly informative, it is merely the "challenge" that generates the interest.
Exactly the challenge. I am pretty sure that I read they took http://en.wikipedia.org/wiki/Zipf%27s_law and applied it to the distrobution of words/letters and found that it does not match up with what people would call a language.
Aliens are as likely an explanation as anything found so far. Given that no other examples of this language have been found it's hard to imagine it could be any real human one.
I think it's very easy to imagine that a real human wrote this book, since it's right in line with the materials available in the period. It's not written with some futuristic material like say... laser printer toner. Just because we can't translate something (which may just be gibberish) that doesn't prove the existence of aliens.
