livecd + full OS

hi, my interest in genode would be to be able to use it on top of a linux system to run other OS's securely in a virtualised environment. some questions

when will the next live cd be available?

will genode be able to perform any better, or provide any better security, than other virtualisation softwares like vmware and xen?

How do you plan to eventually release a "fully functional general-purpose OS" when the genode code is so small, and it is mainly a userland project?

thanks
