Found this under google-chrome extensions. Let me know if you use CAD and love this as much as I do. It's CloudCAD!!!! save your drawings online automagically and access or upload more from anywhere

The only drawback is the 200 selection limit, which for me only comes in to play their ridiculous samples. Awesome tho, I love having some type of autocad that runs natively.
Here it is under debian stable thru google-chrome
edit: almost forgot to mention. IT'S FREE!!
