I have a lot of experience using ObjectConnect.  Under the covers, it saves 
it (whatever) to an internal save file, sends it to the other system, 
restores it, deletes the save file, and sends the completion messages back 
to the sending system.

Now, the last phrase is the rub.  Because it waits for the restore to 
complete, and sends back the messages, it can take much longer than doing 
it yourself.  But when you do it yourself, you can be multitasking, and you 
know exactly what part of the delay is the transmission time.
