I thought I should tell you about this...
A home 3D printer, the "Cocoon Create" is on the market in Australia. The product is described on their website here: http://www.cocooncreate.com.au . It's distributed by a company called Winplus, and it was available at Aldi supermarkets last week.
To my mind the style of the Cocoon Create logo is very similar to that of the Apache Cocoon project. The "Cocoon" word is fairly generic and I doubt you'd object to its use for a product that's not connected with Apache Cocoon. The visual style is another matter. If the Project Management Committee agrees, I suggest you ask Winplus to change the appearance of their logo.
