If you want to share your data over the internet you kinda need to send it out at one time or another. This traffic can always be intercepted and stored for later use.
I was talking about the part where people use Aero for their personal backups and syncing their own machines, not about sharing with other people.
With something like dropbox traffic goes between me and their servers and whoever is listening in between there.
The way I understand it, with Aero it will go through P2P even if I am just syncing my own machines since both are likely to be behind some sort of NAT or firewall.
