So i have recently found a study that was done by a solid plaster teacher at TAFE on lime renders, describing all of its history in Australia, as well as the benefits the product has. The history especially in the Sydney region really provides solid evidence of how long these products have been around and how long they will last! There is also another document from an American company for you to view as well, stating many of the same facts.
The american company who wrote the second document is http://www.vero-rialto.com/lime_history.htm
The company who commissioned the other study is http://glassford.com.au/main/https://
There are strawbale homes being built all over Australia now, and they render the entire interior and exterior and bathrooms in Lime. It is a proven building material, and their documentation written by a TAFE professor helped them to prove that it is in fact the best out there. Make sure you read this, and see why lime beats all the rest!
