Sure.

I think this should be easy.

Easy, though having nice axes might be a bit more work. I'm guessing  
you're thinking of the "bounding box" style axes, not the x/y/z-axis  
arrows.

This is the really hard part, but I've got some ideas.

See http://sagetrac.org/sage_trac/ticket/1537 This may involve  
actually getting into the jmol source. Smaller triangles could help  
mitigate the effect too.

I hope so. This isn't a good sign...

I don't think embedded applets can be resized--but it's been a long  
time since I've used java intensively. I'll look into it--perhaps  
things have changed. That's I think the biggest plus of a floating  
window.
