VMS - Language Families Casting

[MarcoP]

Hi Gavin,
here is my point of view:

1. Are there any language families, which are completely impossible as VMS language and if yes, why?

Nothing is "completely impossible", but I think that American languages are nearly impossible. I tend to totally ignore that option.

2. Is it possible, that the VMS, as we know it today, could be a copy of an older book?

Yes, of course. Why not?

3. Are there any living or dead language families, which are "hot candidates" for the VMS language and if yes, why?

I believe that reduplication (the exact consecutive repetition of one word, like daiin daiin) is a linguistic feature of Voynichese. I consider languages with extensive reduplication somehow "hotter".

4. Could you imagine, that somebody from the "Old World" (Europe, Asia, Africa) would "encode" a manuscript, at the time around 1000 - 1500 AD, to hide discoveries in the "New World" (America)?

No, but my imagination is quite limited.

5. Is it absolutely clear, that Rudolf II. and Jacobus de Tepenece were the first owners of the manuscript or do we know more about the VMS owners today?

They are the first documented owners, but, before them, there must have been several others, during the 200 years between the creation of the manuscript and Rudolf's times.
