Would it be interesting to download an run a .dcupdate file for a program which is not installed yet - which launches dcupdater and let dcupdater install the program?
That way you'd never have to point to the executable and the installation could be zero-click. That's pretty amazing.
I guess it would work without much extra development for programs that have an installer, and that .dcupdate files for zipped archives would be installed inside a MyDocuments\DcupdaterApps\<zipfilename> if a default path is not set within dcupdater (as its a portable app).
Imagine all coding snacks pointing to a dcupdate file, wow.
