Tom,

Great questions. I'm not experienced, but do have some friends in the industry that have given me advice.

Here's some countries I've been told could answer at least the majority of your concerns:

Panama
Cook Islands
Isle of Man
Sweden (hear they have good laws in regards to porn, not so sure about their taxation system)

We are currently seeking a similar solution and looking at different options as well. Hope to get some more help from this thread.

Cheers
