CGTalk - MR alpha missing

greetings to all.
I'm getting into MR (with Maya 6.0[1]), so actually I'm exploring the fast_misss* shaders. first of all I wrote a mel-script which automatically will set up working hypershade-network which one then would use as a starting point to set up a skinshadind-network...

after playing around with the different settings I realised, that in the framebuffer alpha is missing although in MR render globals framebuffer is set to "RGBA/Gamma 1/colorclip Raw".

I'm aware, that using MR-nodes within Maya isn't that comfortable. but I rally like to go behind the scenes. so if anyone could give hints here and there, I'd really appreciate that...

cheers
