Of course it is! We covered much of this in 
1998.  The new things are increased frustration 
and possibility that with current technology and 
mindset we might actually put it to rest

Yes, so do I.

The vision is of a generic client onto which 
domain specific facilities can be installed.

Thanks for the suggestion. I am sure that web3d 
will have use here. But the viewer needs to have 
a lot of chemical semantics. We already have that 
in Jmol which performs as well as many 
hardware-accelerated alternatives. Note that 2D 
is complementary to 3D in chemistry - both are essential.
