Hi Miguel, its a little late but I found a Framework named Draw2d for Javascript based drawing. http://draw2d.org/draw2d/
The Examples are really nice and show the power and possibilities of the framework. http://draw2d.org/draw2d/examples_short Maybe you can use some parts of that or get some ideas from it.
