That is correct.

Q: What is the difference between 'pmesh' and 'tmesh' ?

Googling on those term turned up little more than Prof. Johnston's page
mentioned above.

Q: What is your timeframe for development/deployment of this website?

This item is on the Jmol task list. I hope to implement it within the next
4 to 6 months.

If you were in a position to help fund the development of this feature
then the priority could/would be raised.

I do not think that you are reading the files using *JavaScript*. Rather,
I assume you are reading the files through the Chime plug-in.

An 'unsigned/untrusted' applet cannot read from the local file system.
That would be a security violation.

Several people have requested a 'signed' Jmol applet that would allow
access to the local file system. This would allow:
 - access to the local hard drive
 - CD-ROM distribution of browser-based applications
 - access to secondary web servers ... for example, loading
   files directly from the PDB.

In addition to the direct engineering resources required to implement and
test this, there will be a direct external cost; doing a signed Jmol
applet correctly will involve buying a code signing certificate from a
recognized certifying authority.

Again, if you were in a position to help fund some of this development it
would be greatly appreciated.
