Remoting vs Sockets

Hi,
I'm building an application for versioning purpose.
Though this versioning system is different from our regular software versioning applications like WinCvs, VSS etc (as my versioning system has more of the domain essence to it), the basic architecture would still remain same.
There is our client application containing some versionable elements, from which we trigger new versions, which would be stored in a repository at a server.
Here I'm stuck with the communication channel. I've figured out 2 ways of doing it
1. Using sockets
2. Remoting

Primarily there is only transfer of files involved between the client and the server.
I'd like to know which is the better way to go about it.
Also is there any other approach apart from remoting and sockets to form a client - server app with this kind of requirements?

Thanks in advance
