It really depends, I think. If you know the person or has a very good recommendation from a friend, then Id test it out. I am currently working on a friend of a friend (recommended highly by the latter friend) who resides in NZ (I am in sydney). Comms is a problem. It is a very new thing but I could really use his presence in Sydney.

But I am new to this game, so I cant tell you the otherside of the story.
