	Yes. Of course you should use an ample sized buffer.

	Yes. There is an SMB_COM_COPY command that will do this without going
	through the client (as long as the file is copied to the same host) but it is not
	supported by jCIFS at the moment. Actually the SMB_COM_COPY code is
	there (see SmbComCopy.jav) but I just never added a copyTo method because
	File and XFile etc didn't have it. It will be added to 0.6 but I want to optimise for 
	opying large quantities of files and directories across hosts (something most
	CIFS clients do no do or do not do well).
