This is exactly what I use Live Mesh for. I sync 10s of gigs of photos between remote PCs with it.

The only thing I don't like about Live Mesh is that it's very difficult to tell what it's transferring and how long it's taking. It works, but I wouldn't be able to tell you "it'll be another 20 minutes before it's done".

How does AeroFS stack up here?

There's a window with a list of current transfers with progress, speed and an ETA per transfer, but no global ETA (yet).
