I believe that both use Google web toolkit (which resolves queries that are then converted to HTML in the browsed rather than serve formatted html data direct from the core) but whilst Control:Web is a web app, both Control:PC and Control:Web are 'native' apps that have a 'web window' to the same tools that Control:Web do. Outside the 'web window' Control:PC/Control:Mac offer other functions, which includes a 'Sooloos hardware device' like protocol for audio rather than http web based audio.

So think of Control:Web as a web app and Control:PC/Control:Mac as a browser that runs a similar (possibly even identical) web app that Control:Web runs plus a whole host of non web functions.
