Well, if you can do it, that's great. The videos look terrific.

ChemDoodle is using WebGL with a Java-based server application essentially
(if not exactly?) Jmol. The library is not proprietary -- it is open
JavaScript. But the connection to their server is proprietary. Anyone could
reroute that to another server, I think, and for example drive Jmol with
it. They feed all information to the client, and the client processes the
data. Last I saw, they didn't have molecular surfaces.
Right, small proteins, no problem. I saw only crashes with larger proteins.
That may have improved.
The solution of having most of the operation on a server is certainly one
solution, maybe the only solution for WebGL and Mac iOS. I don't know.
