In my opinion, one of the biggest advantages of Amber is that you don't need any particular web server or backend. A web browser is everything you need and the whole Smalltalk VM is running in the web browser (it's also much easier to set up). I'm also wondering whether remote rendering is fast enough. You need to talk to the server on every event (mouse click, mouse move (this is really expensive), keyboard, ...) and every primitive you render must be sent to the client. yes, and in that regard, http://gsoc2013.esug.org/projects/athens-html5-canvas is way better alternative.
OK, I'm getting the feeling that it's probably best to implement a proper HTML Canvas rendering engine (Athens) first and build a Morphic(-like) framework (e.g. the morphs from Cuis) on top of that afterwards. Having a good architecture is more important to me than getting results as fast as possible. -- Matthias Springer * me@matthiasspringer.de * +49-1577-3814255 Student B.Sc.
