XProtector is nice protection too. But its doesn't have many features like other commercial products. I don't like some other things about it (compatibility problems, big loader and other things). But here is not automatic tool for it.

The versions before 1.05 were very feature limited.
But in version 1.05 they have added a lot of new features like hardware-locked-licenses.

Also Xtreme-Protector has not been unpacked so far .
Neither by a cracker nor by an unpacker.

@Squidge:
What do you mean with "Instability engine" :?
For me it's working fine....
(Ok, I could not protect any command-line apps; but I can protect any other gui app w/0 probs)
