Thanks for that! I found the zipping reference and got it to work.
Returning now to the example above ("texmfstart
texexec --lua --environments=myfile.tex someotherfile.zip"), what I would
like to do is using lua in "myfile.tex" to extract the filename to be texed
(someotherfile.zip) and rewrite it on the fly to a zip-archive content
along the lines of
\input zip::someotherfile.zip::somezipcontent.tex

Is that possible? "texmfstart texexec --verbose" produces something like
TeXExec | option 'filename' is set to 'someotherfile.tex', so how to access
this during processing using lua?

Thanks for any insights,
