This "try before you buy" contractor meme is awful. 1099s are responsible for their own payroll taxes and their own health insurance. If a company suggested that I relocate for the opportunity to consult with them, I'd hang up the phone. It's insulting.
(Obviously, I mean, as a half-measure before extending a full-time offer. If a company suggested that Matasano consult for them, we'd thank them and then make it happen.)
