Thanks to Eric and Ars, I’ve found Dropbox. A great product. Sync and share your files among multiple computers.
I’ve been using Live Mesh for a while now, but it had its flaws. Mainly it didn’t work in Linux, and thus making file syncing pretty sucky. Dropbox not only has Windows support but also Linux and OS X.
Of course I’m writing this all up before I’ve even used it. But that Linux support is the key that Live Mesh has been missing. Live Mesh does have rdesktop feature between logged in machines, which is nice. But this is the way to go with file syncing.
