Comment 9 for bug 570747

Beyond if this goes to Lucid or not, we're needing this. After this is coded, it may go back to Lucid, and will not break anything (just two new signals).

This will make a noisier DBus yes, but if we don't have this, people will start to poll the syncdaemon for updates (Rhythmbox already polls it).

So, it's better to have a DBus signal propagated that 1, 2, or more processes polling for news.

OTOH, Samuele, you can just send the signal after a relevant change... you should want to know how a upload or download is progressing if the file is big, so issuing a signal only if changed a big block like 64KB, not each time a kilobyte is sent or received (note that I don't know now the granularity of action queue's queues here).
