Thanks for the tip. I&#x27;ll try to watch for that. Confirms it&#x27;s already practical for at least graphic presentations. Meanwhile, I wonder what the odds are of getting a hold of Frank to play with it or build on it. Might have to try to contact him.<p>Note: I thought about doing something similar in first secure desktop I construct where I do my presentation on it, let people counter the methods probably won&#x27;t work, and then tell them after that. Always priceless faces when that happens. Also helps tell the contrarian bullshitters apart from those who think hard on your claims. Saves time in future. ;)
