There wouldn't even be the need for MyWorkspace at all, since we have Home: for the same purpose. And, inside Home:, all Ubuntu-derived distributions already place the same subdirectories for user projects, so there is really no need to recreate them. So, starting with Icaros 2.3.0, hosted installations will use these folders instead. Unluckily, changing some ASSIGNs is not enough, because Linux and Windows behave differently and, worst of all, directory names change when setting a different locale. So, for instance, your $HOME/Pictures directory becomes $HOME/Immagini when switching to italian language. This means that if you change language in Linux, your Icaros installation has to reflect your change immediately or, at least, at the very next session.
This is, exactly, what I am working on these days and, after a lot of scripting, it's what I'm getting right now on my development machine. I still have to decide if this will lead to some new ability also for native users: after all, once the gears are there for a more dyamic management of MyWorkspace on hosted, it shouldn't be difficult to give native users - at least - the chance to modify names for the same directories.
By the way, our integration effort goes far beyond this. I can not officially announce or anticipate anything at the moment, but if you follow our facebook channel, you may see some very exciting screenshots released from time to time... Like these ones:
