Wary64 has the same code-base as April64. The only difference is smaller size, which is mostly achieved by providing a small subset of the Xorg drivers -- in particular, there is no llvm, mesa, opengl.
I also left out Qt4, which is required for the VLC media player. However, I discovered that the Xine media player, which only requires Xlib (not GTK or Qt libs), plays all of my test videos. Xine is small, and works well with external ffmpeg libs.
A couple of packages not there are samba and pidgin. Instead of the latter, SeaMonkey provides IRC chat.
I also took out some less-needed kernel modules. This is what we used to call the "zdrv"
