To clarify my position:
I currently make money selling digital products through my own website and through eBay.
Any sales which come through my website are fully automated, the customer chooses what they want, pay through paypal and they receive an email fro the site containing a temporary download link, first time I know I have sold a product is when I get a notification email from paypal saying that I have new funds.
eBay sales, I simply send a pre-formatted email in reply to the paypal receipt which either has the file attached or (if too large to email) a temporary download link.
From the sounds of of neither of those instances would require a work visa.
As for travelling plans, I want the freedom to be able to go wherever the wind takes me. Pardon the deliberate pun
I will most likely visit the med first (first long distance cruise).
But I would very much like to visit US waters, key west and sail on the bahamas, Caribbean and Hawaii
Aside from digital sales, I am working hard to launch a children's foundation in the UK, a unique 'self-funding' charity project designed to make a difference in the lives of local children.
I had/have plans to bring the project to the US in the next few years but it seems that there may be possibility to bring that timeline forwards somewhat in which case that would complicate matters ever further.
If things pan out that way then It is highly likely that I will come out the US via 747 and leave via sailboat...
