This is really a nice idea.

I don't want to leave my empeg playing when I don't use it, because I don't want to hurt it too much. So why don't you let the emptool scan partitially or all tracks and synchronize the profiles with the empeg? The PC is (in most cases) much faster than the empeg and can do more jobs at the same time and it is much easier to implement it in the emplode gui.
Lets think about that...
