I know that if I just copy the files, you don’t see them on the receiving system.

So have I.  But I think it has problems.  As it is at present it the 
'recordedid' value is imported with every file, but different systems 
increment the value independently - and it is now the primary database 
sorting key.  I would love to have a safe way of merging independent 
databases;  I haven't found it yet.
