I think File::Copy handles UNC paths. (In the cygwin perl (the one I use) I believe that filename resolution is ultimately passed on to the OS, so it has access to all the files the OS does.)

I don't know about the recursive add-on, but I figure while you're doing your File::Find, your original routine has access to the full path of the filename. Given that, you could copy it over to the destination device.
