Have there been any non-Apple apps, specifically open source applications, that are able to use the latest iTunes sharing protocol? I remember trying to find something like this, but it seemed that nothing was able to communicate with iTunes 7, because of what Marcelo was talking about. If that's still the case, then getting it to work in Canola would seem to be a pretty small chance. I ended up moving away from iTunes and Apple's Lossless codec for this very reason.
