We (@ arm) are also interested in contributing MCTP to OpenBMC.
We are in the process of getting CLA signed.
We have the same concern regarding duplicating work.
We would like to collaborate with OpenBMC folks  who are interested in this topic. (maybe form a Workgroup to discuss this).

Us too! I'm interested in looking at MCTP, and am in the middle of doing a little prototyping with our host firmware stack.

I'd also like to avoid duplicating work though, have you (or others) made progress on this since this initial email? I know there was a presentation on MCTP at the recent hackathon, but I'm not sure if any solid plans came from that.

If not, I'd be happy to sketch out an architecture for this...
