[ale] vmware kernel

[Geoffrey]

I've been doing some research on vmware in order to compare it to Xen, 
and can't seem to find a critical piece of info I'm looking for.  As I 
recall, vmware is based on a linux kernel, thus the following questions:

1. Is vmware still based on Linux?
2. Why do they not publish their code?
3. Is it possible it's based on another OS, say, bsd?
