Paul, 1) Removing the flicker idea is good. We'll see about implementing that. 2) Tell me if the following is what your envision. *You want a link you can use to download the file generated for Jmol in SAGE. *You want that file to work in the Jmol application (or is it the applet) no matter where you put it.
The first part is really easy. The second part is a bit harder. Jmol can generate this kind of file from loaded data, but we will have to rewrite the SAGE code that generates the files for Jmol to get those kinds of files on the server. That is why I suggested the signed applet. Since they are allowed to write to the local disc if the user agrees, they can take whatever data is in them and generate a file you can move around. If you are doing this all inside a web application, there are other ways to do this from javascript. You would just have to move data generated in javascript to the server. Jmol can generate a "state" script, which would point to all the necessary data on the server (assuming it is the same one, otherwise you have to use the signed applet). That script is all that would have to be moved into the homework. The other issue is getting Jmol to behave within the WebWork framework. I don't know what those requirements are. I know from discussions with other people that you have to be very careful when embedding Jmol in things like Moodle and Wiki sites.
