it's in very early beta stages but i been using it for a month now. basically mesh allows you to add any kind of device (ppc, laptop, desktop, etc) and allow them to stay synchronized.
for example, i put music in my desktop folder and a few minutes later its synchronized to my device. this is really good if you have friends with a ppc. everyone "shares" a directory and all devices synch up to all have the music.
there is a bunch of other stuff like remote desktop to any pc on your mesh, virtually... you also get 5GB~ to store whatever.
im not sure how long the waiting list is, but i got in a month ago.
