Answer 2

“On what” is an eternal question in such cases, which almost does not make sense, because it is the specialist who decides, and not the customer. Although in this particular case such a question makes sense, but in the reverse form: "on what should not be done." The answer is don't do it in Flash or Java. From the developer, in this case, experience is required in the development and support of interactive 3D applications running in the browser.
