So if I understand the purpose is to evaluate source-code blocks in
Org-mode files which will open terminals in new windows, send shell
commands to those terminals, and either display information in the
terminals and possible insert output from those terminals into Org-mode
buffers?

I like the idea, however I can't get it working on my Mac.  I am able to
pop open new xterms, however nothing seems to make it into or out of
screen (maybe this is because I all ways have screen running as my
normal terminal emulator?).

Unfortunately I'm *really* short on time right now, but I hope to take a
closer look when I get a chance...

Yes, the code looks clean, and it looks like it would provide a new type
of functionality (live terminal output?) so I'd be very happy to include
this into Org-babel.

I don't see where you have /bin/zsh hard-coded...
