I've met with publisher A (AKA "dream publisher"), and they seem interested based on the proposal. I have to see publishers B & C still; and I made a preliminary contact with publisher D, who seemed more tepid... but the editor was British, and I may have been incoherent.
Once I've had all my meetings, I'll let you all know what things look like.
In other news: it's 2:30 on Friday, and I still haven't been to a single panel. Oh yeah.
