I would like to disucss the use of the term MODEL in the context of
animations.  is it still appropriate?  does it conflict with the traditional
use of MODEL to mean one possible solution in an ensemble of NMR structure
possibilities?

it was always a kludge in Chime, using MODEL to implement multiple frames.
essentially the 'proper' NMR file format was hijacked to build scriptable
animations of macromolecules.  perhaps the NMR experts could provide some
opinions here?  do you see this as a potential conflict?

if so, one idea is to implement a global script command to act as a switch;
for example,

   set models nmr|anim

this would tell Jmol whether to intepret MODELs as frames in an animation, or
separate structure solutions.  or does this seem unnecessary?  (I am in favor
of KISS - keep it simple stupid - but we should be sure we aren't crossing
any lines.)
