Parallels is Awful?

I was just poking around with Parallels on my Mac once again, while discussing a weird bug in Ruby with my old friend Aaron. He wrote up a little security analysis on Parallels here. I have to say that it's worth looking at if you're into security and you have a Mac. It has scared me enough to remove Parallels from my machine.

The jist of it is that, the way Parallels works opens up your machine in a bad way -- someone could possibly write new functions and insert them into kernel space (where they would run with absolute privelege to do anything), and then they could call that new function and do all sorts of fun things -- anything that your hardware is capable of doing, that userspace program could then do. Not very good for security...
