I don't understand what problem you see.

To write a curses-like UI you simply read keyboard input from stdin, and you issue "drawing commands" to stdout. When deploying you would run the VM headlessly, and while developing you would just use the regular Squeak GUI to write your code, and at the same time stdin/stdout to test your app. No need to "emulate a terminal" because you have the real terminal right there. Ot at least what counts as a real terminal nowadays ;)
