I decided I had a little time to start looking at this. I'm not very deep into it yet...extracted the second app :P but it's a VERY interesting crackme. I'm sure this will be a fun one!!

I know a lot about different pieces of this crackme but I still have not been able to solve it :( Too bad patches are not allowed :P I get confused when the child process read the memory of the parent process. So far, pausing the app when it's executing and attaching to it with a debugger that can modify the registers after the ptrace call seems to be where I am at now but have not been able to figure out what exactly it's looking for.... sigh.

Good crackme crp-!!! :)
