We plan to release Jmol version 6 within the next few weeks.
One of the goals of this release is to support more file formats.

I have not been working on file formats, so I am not sure. But unless
there is some great obstacle, support for this file format will be in this
release. I will check with one of the crystalography people to confirm.

Well, the measurement capabilities *will* be in the next release of the
applet, but they may not be that easy to get to.

For this release we have put in rather broad support for RasMol/Chime
scripting. Thus, from a script you can create a measurement between atoms
(the RasMol scripting language uses the term "monitor").

However, for this release we do *not* plan to have user-interface gestures
which would allow a user to apply measurements interactively with the
mouse. This will need to wait for the next release.

I am not a chemist, let along a crystalographer, so I am not sure I
understand the problem/question.

Is it the case that you want:
  distance 1.523 +/- .05 angstroms
  angle    45 +/- 4 degrees
?

Part of our goal is to make the applet more robust. As we add
functionality we want to enhance both the application and the applet.
