Ideally you'd want a business entity that is as inexpensive as possible to maintain but provides liability protection in case you're sued. Then you need to consider where you will be "registering" this business (apart from the original country) as a foreign company because that will involve expenses, tax, etc. Finally, if you're just one person, not really renting offices, not really hiring employees in the country where you are operating you need to ask yourself do you need to really register in that country as a foreign company and who would know if you didn't.

My company has been thinking of creating a sort of "world company" package for people like you: solid main entity (Wyoming LLC for example); globally accessed banking, mail scanning/forwarding, etc. I'm curious if that would appeal to you (or anybody else on HN). Email me mattknee at google's mail system if so.
