A couple of points about cooking sous vide. Firstly, it happens far more than you might think, you just don't happen to have read about it as the "latest thing". Thermostatic water baths for cooking at 62C are almost commonplace in professional restaurant supplies. Low temperature roasting is commonly done, for example to give perfectly rare roast beef for sandwich bars etc. So although WE as ordinary people, may not have heard much about it, it is used more and more because it gives wonderful results, and also frees the chef from worrying too much about timing. Let's face it, if cooking 20 hours, it won't really matter much if it's 19 or 23.
I've been fortunate enough to eat at two places where this cooking technique was carried out by a master. In both, the results obtained are magic. However, I'm not altogether convinced what it would do for sausages.
