I think once GNOME and KDE bloat to one gig+ live-cds, LXDE will
become the only choice for those without dvd burners or huge thumb
drives...
Seeing how small LXDE-live is, and how easily the Security Spin was
stacked on top of it (I'm guessing), I think LXDE-desktop could become
a spin of remixes...
A CLI retro terminator remix...
A light, but GUI, LAMP+X+panel
A live cd with OOo and GIMP full (no longer exist on one live cd)
