remote windows

Is is possible to open a standard browser window using without specifying a url and then from the opener, use js to add a dthmlx layout.

Would you recommend using document.write to create a div in the remote window and then add a layout to that div.

I suppose it would get tricky keeping track of layout/forms inside the remote window once multiple windows were opened.

After researching this for a bit, it is not necessary at the moment.
