We don't want to get too far afield with operating system details, but 
the 'problem' with ls and the 'shell' issues mentioned in an earlier 
note are things like ls doing a qsort by default on filenames before 
returning them and operating system limitations of command line length.  
While in Unix/Linux command line length is relatively huge, wildcards 
must be expanded by the shell before being passed to a command like ls 
which isn't reasonable when the list needs to be gigantic.  As a result, 
you need to use commands like 'find' and 'xargs' when dealing with large 
numbers of files.

I believe that JAR files are usually compressed zip files, although 
certainly the components don't need to be compressed.

The problem I have with the ZIP file format approach to representing 
arbitrary XML is that it's not going to be efficient for every case.
Some of the characteristics that make it somewhat useful should be 
considered in a new format, but it is designed for the granularity of 
files, not tags, and it doesn't seem especially elegant for representing 
many proposed instances of data.
