I'm still playing and, like a true user, I haven't read up on how the communication is happening in the background. Essentially though you run a client that uses your MS credentials to authenticate to your mesh. I'm assuming this means encrypted via 443 but, again, haven't read yet. Also, you can just connect to your mesh and grab files from any device but this is merely a SSL connection with login/pw on a web site. I'll definitely post more as I discover the info.
Cool feature #2 (number 1 being the data synch), integrated desktop conenctivity (via RDP?). Login to your Mesh site, select one of the devices on your Mesh, hit Connect and you are remotely controlling the device in the same way as GoToMyPC/RDP/PC Anywhere/Etc.
