We don't have plans for the "Chimera Lite" you describe, but we do
have some plans that nonetheless may be of some help. One thing we
have right now (in the 1.6 daily build) is "WebGL" export [under
File...Export], which modern browsers can show directly without any
plug-ins (though many browsers currently need to have this cutting-
edge capability explicitly "turned on" by the user, see:
get.webgl.org). This may be more convenient than showing VRML. The
generated HTML file, when shown in a browser, supports the normal
"embedded trackball" Chimera mouse motions for rotating and scaling.
We are actively working on improving the performance of exported
WebGL, but it still can be slow for large systems.
We also intend to leverage WebGL further and implement a subset of
Chimera directly as HTML displayable in modern web browsers. This
will take some time to get going and even then display of trajectories
is doubtful. It's a lot closer to your Chimera Lite idea though.

P.S. Thanks for the compliments in the original mail! I trimmed them
off the above so that other people just got the "meat". :-)
