Hi Rainman... If I follow the link that Easypano posted to Troy you'll see that the company that did some of the Rendering work for Try states that they used Easypanos PW. It doen't mention virtual tours... then again... stiched images are not just used for Tours... which is what is mentioned and stated in the article.
As far as the FBI is concerned... well I doubt that the FBI is willing to allow any images they shoot to be used for reference work. Therefore proof won't be forthcoming. Then again... I'd imagine that the FBI would probably lean on Easypano if they were to claim something thats not quite the truth.
I can understand where ur coming from... At the end of the day however, you need to decide if you want to use the software which works well and is effective. You want to ask yourself if Realtor.com who, as far as I understand it had a "only Ip*x images" agreement, would be willing to let Easypanos products be used on their site. This, if not legal, would surly reflect badly on their product. Furthermore, TW doesn't infringe on anything as far as I'm aware. I believe the debate centers around the stiching of 2 hemispheres. Stich 3 and that problem, if it is one, is solved. If unsure about that... well stich ur panos using something else and decide if TW is for u or not.
For me it works and is a good product range.. and thats from somebody who was also concerned about the legalities and having researched the issue found my perceived risk to be minimal.
PS. I'm not in anyway affiliated to Easypano... I'm just a satisfied user who has a product that works and couldn't care less if they declared they flew to the moon to take panos or not. ;-)
If I only had an hour to chop down a tree... I'd spend 45 mins sharpening the axe.
