Is it? Since Adobe switched to the subscription model and the "Adobe Creative Cloud" I'd say they would be quite happy if that infrastructure would be good enough to run their very big application suite(s). Not to mention the savings of not having to support two major platforms (and several OS versions for each) - even realizing them only partially would be big. Of course, given the size of their product I'd say there is little use in talking about this at this point, the web platform would have to mature a lot more first.
