important missing functionality: shortcuts?
there seems to be an important part of desktop integration that has been missed out:
* providing shortcuts on the desktop, or application menu (these have meanings under Windows, GNOME 1.X, GNOME 2.0, KDE, CDE and the freedesktop.org initiative)
* providing application management integration (eg Add/Remove programs on windows, not sure about other desktop systems)
WebStart does this, but commercial products are often still distributed on CDs
