I suppose that depends on how remote you want to be and what their availability is for occasional on site work. I've worked several places where I've done work remotely that was integrated on one specific, specialized system. I did most of the work remotely and then every once in awhile we booked a hotel close to the final site and did a week of testing. It requires a lot more up front planning. It doesn't work as well for an "agile" environment. Although from what I have seen it is difficult to make "agile" work in a specialized hardware environment anyway.
