I've probably seen (or answered) some of your questions on the Hugin google group....
Anyway, 2 years? I wish you had come out sooner, I or someone else out there would have been happy to help you speed things up a bit. I know the satisfaction of having done it all yourself though, of course!
And yes, I have been dreaming about doing the same thing for a few years.... so, my hat goes off to you for executing this really nicely.
And I haven't been totally silent on it. I have been posting regular updates on my G+ page pretty much all along.
What happened to your website links? Could you email them? I've been busy and only remember you had some.
Sorry I deleted my links, I was one of the first comments and just wanted to compliment you without appearing like publicizing myself. I'm founder of 360cities.net, panomonkey.com and sphericam.com. I wish you had contacted me before, even if you wanted to fly solo on your project I would have been happy to at least point you in the right direction on some stuff. :) Please do contact me at 360cities on the g mail domain or skype jeffrey.s.martin, would love to hear more!
