I understand. I have basically seen in your work more or less the same 
approach as far as TPM class.
I believe, according to your plan, i can wait for you to update you tree 
integrating my first comments on tpm-working branch or
if you prefer i can send a merge between your work and my comments.

What's your prefered option ?
