From the developer:
The Secure Download Manager (SDM) is e-academy’s proprietary software program for managing the secure download of files from the software.caltech.edu webstore. When you download software with the new SDM for the first time, you will be prompted to download and install the SDM on to your computer. This differs from the previous version greatly, as before one download client was needed per software title.
