A new PCB design web application was released this last week called PCBWeb. The website states that PCBWeb is a free browser-based CAD application for designing and manufacturing electronics hardware. The tool is currently released in BETA and allows you to create a schematic, full circuit board layout, and then export to gerber format for manufacturing. The application is supported on Windows and Mac using Silverlight.
