JFTP: It must be .desktop. In Debian (KDE 3.2) the right path to install
<app>.desktop is ~/.kde/share/applnk/<categories> and for
<mime-type>.desktop ~/.kde/share/mimelnk/?

I saw it. A new Debian-package will be available soon.

I'm not completely sure, if we need the .keys and .mime-file
(/usr/share/(gnome/)mime-info/*) too, for Gnome. But I will test it. For
the moment, they are included in the Debian jchempaint-package.

The third file updates /etc/mailcap (part of the mime-support package),
a configuration-file for the metamail-program, which determines how to
display non-text at the local site (see man mailcap and man metamail). 
This is used by e.g. mutt and IMHO mozilla-firefox. It works on Debian.
If someone can test it on SuSE or any other linux distribution, this
would be great.

The shared MIME-info database is AFAIK part of ROX-desktop. So the
chemicalMIME.xml can also be used for ROX-desktop. But I don't know, if
this is enough to make ROX-filer recognize the chemical MIME types
(there are AFAIK only out-of-date Debian-packages for ROX, so I can't
test it).

One thing: The /etc/mime.types (also part of mime-support) does only
contain x-pdb and x-xyz. So I will write to the maintainers of
mime-support, if they can add all the mime-types in the
chemicalMIME-package. To make it easier for them, I will uploaded a
patch-file. I don't know, if SuSE or RH or any other linux distribution
also provides such a package. So this is only for Debian at the moment.
