They surprised me! Project Bento, server side, arrived at the main grid Tuesday. Torley Linden has posted about the Lab enabling the project on the main grid. See: Project Bento Testing Is Now Live on the Main Grid!
This is a testing release. You will need the Project Bento Viewer to upload animations and meshes, and to view them without distortion. Bento mesh weighted to the new bones looks horribly distorted in non-Bento viewers. Expect to see lots of questions in the forum about how to fix the problem.
Just send them to the Linden announcement… or here.
