I was just going to say I don't see any practical use-case, but you outlined one I didn't think of. One problem I foresee is the cross-email compatibility problems. It's a magnitude worse than browsers. This problem is obviously extenuated by the fact that misalignment could produce unrecognizable images. Assuming the technical side is rock solid, I could see people using this for logos in their email signatures along with social icons. I still don't see many people paying for this, much less understanding it. I also hate seeing company logos and facebook icons in email signatures since I just think it's useless and annoying.
