I have just noticed that CambridgeSoft have released Chem3D Net plugin. It supports many types of chemical MIME type files, and the display allows various interesting features not supported by other software, ie the ability to measure geometries. It also reads Gaussian checkpoint files, and allows surface rendering etc. Both Mac and PC versions appear available. Chem3D Net does not however appear to support Rasmol/CSML scripts, and thus all those nifty buttons to highlite functional groups etc that some people have authored to work with eg Chime will not work. It appears to be compatible at the HTML level with eg Chime. Invoke http://www.camsoft.com/plugins/ and click on "Free downloads" Dr Henry Rzepa, Dept.
