It sounds like the issue on using an HTTP PUT is whether the NT server supports
it, since that's the destination system.
As to the socket vs RMI question, let me add to Craig's summary that RMI uses
Java serialization which can result in a large amount of data overhead. If you
read the file in and then send it across as a single large String the RMI
overhead should be minimal, but RMI seems to gain you little in the situation
you've described anyway. If you can't use an HTTP PUT I'd recommend a socket
connection.
