Scope out a Porter-coat extension

[squillace]

I don't think we can continue to build and extend duffle-coat. it works great. But once duffle is 1.0, and duffle coat works as it does, I think we need a porter-coat -- or at least we need to understand how to do porter coat, what the ramifications are for size, perf, and engineering resources.

not sure but I think @carolynvs has a way to go at this. @itowlson the actual use-case is NOT that porter should be there -- that's one implementation -- but rather that subsequent viewing in porter of installs should be possible. one way would be to have porter view duffle artifacts, for example.
