I am not sure what mega does... is their source open? I guess I should just try it. My concerns were having a large enough sand box (files could be 1G+, and many of them) and if there is, even for a short time, a 2x storage hit. Then the second hit of copying (not moving) from sandbox to local or remote drive.
