For anyone that might be interested in selective download (download only the files that you want) - Sync 2.0 PRO is offering this feature. The catch is you must buy the PRO version (well you can try the FREE version and get 1 month PRO version for free).
I have updated first post with more data about this.
Due to the ongoings of life I have been a way from rf2 for a while and at the same time have reformatted my HD and reinstalled everything. This includes the BTsync. But, it doesn't seem to be working.
I have did the secret key thing and pointed it at my packages folder and it doesn't seem to be syncinking with anything or body.
