The volume was related to what? Perhaps John Unwins speaking at the FIA conference? Exposure for Spooz in front of a huge audience is helpful by any standard. However, it's pure speculation on my part.
I have attempted to find out as much information about the FIA conference as possible. I know Paul was there, and I'm pretty sure there were audio and perhaps video taken from John Unwins speech at the conference.
When it will become available is not entirely clear, I'll do more to find out. I noticed that past FIA conference audio files are available from the following site.
