L.S., If there's a way to figure out by the data you read if the file is complete, you can always build your own marshaler that extends the BinaryFileMarshaler to figure that out before actually sending the exchange. If you download a new snapshot of ServiceMix, there's a new feature in the FTP poller that checks if the file is still growing in size to check if it's still being uploaded.
The only other solution I see would be by using the upload-then-rename strategy I mention in my previous post.
