Putting them on another server is not possible with this version yet.
The only thing you could do is move them and then link to them. However, that would mean an awfull lot of work if you have a lot of files.
You could do it that way however with new files but only if you add them yourself and not your users, because uploads will still go to the upload directory when they don't know where to link to and how linking is done (you have to calculate the size of the file yourself).
