Yes, they could work from a branch, but then we'd have to give them read-write to the repo. There's no per-branch access control.
Working on a branch in their fork doesn't help. They still can't pull in updates from the original repo.

Still it'd be awesome if GitHub supported this via a Web interface.
I don't see why they can't pull in updates from the original repo. Are they not adding it as a remote?
Because github doesn't provide a way to do that on the site. Git workflows that can be achieved entirely on github.com were that subject of the story, and my original comment.
