Polly try contacting Ian Mock or Harriet Alvis at Bristol Avon RT – their trainer may be prepared to travel.
I haven’t used Realtime board so not sure exactly what functionality it has, but it looks like a project management / team task allocation app? If you want a way to present the ongoing actions and show progress within your story map, then could you embed it on one of the tabs? If you are looking for alternatives, then the only similar thing we’ve tried was Allthings (http://www.allthings.io/) which again you could embed within a tab as an external website. It’s not free, but they did offer a charity discount – I’m afraid I can’t remember the price, but you can try it out for free for a couple of weeks.
