Thank you for the extensive answer, as it is paid service, I would only suggest you pay a bit of money for someone on 99Design to fix your styles. I would love to read more about architecture but as it is commercial product, I understand that is kind of trade secret.

How much time did you spend developing all this? And resource wise how hungry is it? (Servers, Memory, CPU...)

Edit: Wait a sec, I just saw this is part of open source demo of ViewFinderJS, bit confused now, is it commercial or opensource? How do you prevent someone of other 8000ish will not create a bit same and steal your thunder so to say?
