That's not an easy question, but let's say that if there are no big issues with the core syncing functionalities a GUI may appear within two weeks (but don't quote me on this, I did not say it )

The main issue at the moment is that xml.utils.iso8601 stuff that is really worrying me since I can't find a proper pattern for the failure. I will probably install all the packages other people installed to see which one is causing grief....
