The plan is to support gnomevfs before 0.2 if someone gets around to 
implementing it. I was thinking that there should be one class that 
makes a nice abstraction for us. Then you would just do:

import FileOperations
FileOperations.movefile(from_place, to_place)

With this, file operations could try to use gnomevfs and default to 
regular python calls if that doesnt work.
