I keep up on the cracking scene quite a bit. Currently I can't find any ways out there to get around Armadillo v2.01. There are plenty of cracks for earlier versions but none that I can find for current versions.

From what I can tell they really keep up on their product.

Anything can be cracked w/ time there is no 100% fix. But you can make it hard for someone. Armadillo is just one way.
