Only 600MB, you have an easy life.
We have movies that run into 4 GIGS by the time we add the images, samples, full scene, cuts Mpeg and WMV versions.
Only one way to do it, get a decent connection and use something like FileZilla and load them up over night. In the morning everything is done.
Our editor comes in every Monday morning with 4-6 new scenes. By Tuesday they are all up on the site.
