The following packages sould go IMHO.
78M cheese
61M firefox (xulrunner)
14M claws-mail-plugins-bogofilter (bogofilter, gsl, atlas)
6.3M transmission
1.3M iok
Midori should fulfill the browser need on a livecd, after installation
people can install firefox or chrome, if they want another browser.
cheese is just to big for a livecd, for a a webcam app, if people do an
installation, they can add it if they want to.
At bittorrent client is not very usefull on live cd :)
An onscreen keyboard is not used very often .
