It would be nice if it was intergrated as an update to the xmb where we can have an option to stream music from our pcs while doing anything on the ps3. I hope this will be a standard feature that can be implemented on th ps3 and if not it should be a mandatory feature of the ps4. If the engineers from Sony can keep the ps3 up to date with being able to play 3dblurays without the hdmi 1.4 spec and now offer loseless audio by using the cell processor than they can figure out how to be able to stream music directly from the xmb at all times.
The demos of Sonic Generations and Driver San Francisco supports this feature. I just hope the full games of these support this as well
I hope so as well, as I'm interested in Sonic Generations
