I have been doing my research as well. In fact, I found a download link for the demo client, and all it was, was a Windows command line ZIP file. Granted, it may be a place holder file, but still.
What is really interesting on the whole thing... is that it never really "shows" it in action. If it is "so fast" as they say, why not show it in action. Even if it is SLOW, show it in action. Having it BOOT doesn't really prove anything.
I was quite surprised to get a response from them so quickly, but I was equally surprised they didn't seem interested in the publicity that, if indeed this was REAL, they would want in a serious way.
They are also the makers of some PDF2HTML software, I think it's on mbloom.com (using memory only).
How this all unfolds should be interesting non-the-less.
