I tried this as well.
Avoiding the the security risk is appreciated, but the function that we are missing here has incredible potential.
To be able to have a 3D model as a visualization tool and for means of referencing to pdf documents and other files/programs would be the case study of case studies.
I suppose I am stuck with using the ruby script URL. Just have to make sure that others have it installed as well.
I guess I could post the documents to a website, but that increases my security risks.
Don't know what to do, any suggestions?
