You can import SFT files from a DVD!!! Or any media as a matter of fact?
To avoid loading them from a server across the network.
Select an application and use the Import command in the SCS, or you can call SFTTray on the command line (sfttray.exe /load <app name and version> /sftfile <path to SFT file>).
But after you do the import, you will still have to connect briefly to the server to authorize the user to use the application.
The application will load into sftfs.fsd
This will load fully into cache and now requires authorisation to use the application.
This could be presented in a number of different methods including CD, DVD, USB, or other portable media!
