have a look a the softwareUpdater class.

in essence
    you have a list of files
        pha-1232.cs
        pha-1233.cs
       
    ���

    then in the pha-1232.cs you get any smalltalk code

for Pharo, you get instructions to kick a script (method of ScriptLoader)
that will load a list of packages.

I am actually thinking distributing my own pharo distribution for a project I am making called "Ephestos" (for visual and live coding, think of it as a simplification of Pharo with eye candy but of course still very compatible with pharo and squeak) and I wanted to provide to my users a super easy "update" button to do its magic.
