Just wondering, what would you like to see added?
For anything big that I need to leave downloading overnight I still use
WellGet, also last updated in 2005, and it offers a lot more options than ConnectFusion.
Also, both ConnectFusion and WellGet will run without installing, just extract the installers and run the executables. They both leave traces in the registry, (their settings), so can't truly be called portable/stealth.
