I'm sorry not to have seen this post earlier. I hope this response is still timely. - Period Homes, a magazine of resources for residential architects, lists companies who dismantle and reuse barns in every issue.
In my experience (I'm an architect and have converted a barn into a house) the problem with old barns ( beyond Rudy's excellent list) is that their structural integrity is hard to measure by modern engineering standards - something local building inspectors may require.

Thanks for that post, it addresses the question I had posted to the general forum.

You suggest hiring a professional for inspection, do you know people in the Vermont area that do this kind of work?

Also, do you know of any publications on the subject of re-using barn frames for homes? I'd like to delve into this subject a little deeper before I start looking at frames.
