I was playing around with the modified "win" program and I realized it's not going to work due to the propensity of acme to redirect standard error to a separate window. This environment has no way of notifying anyone that a new window has opened without being requested except visually.
A better solution would be to display only a single, border-less terminal window filling the entire screen. Perhaps even multiplexing between a few full-screen terminal windows similar to the ttys available on a *bsd or linux console. Sorry for the noise.
