S3 support is sketchy

This app would be the best S3 interface out there IF it could keep the connections alive long enough to use them. For small files it works peachy king (I copied an iPhoto library with no problems) but as soon as I wanted to transmit a thousand 512mb files it died after the first one. I wanted to store a partitioned zip file of a large backup (~500gb) but I have failed to do so, even after tweaking the settings.
