Stefan--

These are the sort of thoughts I had in mind when I made the suggestion. I 
sort of guessed that someone else may have been down the same path already. 
Any other interest in the topic?

Stefan, is your SCAR material still available?

 Actually, both program use exactly the same format as published for PKZIP,
 so you can (in theory) use any ZIP tool to exact jar files and the other
 way round.
 
 GZIP btw, has the same compression algorithm as PKZIP and GZIP's algorithms
 as extracted in the libz.so or zlib.dll is used by Java's jar tool to do
 the (de)compression.  PKZIP additionally defines an archive format to store
 more than one file in one ZIP file, adding some additional platform
 specific information and comments and so on.
 
 A few months ago I proposed somethings called SCAR (for Squeak Compressed
 ARchive) which used a very simple archive format to store multiple
 compressed or uncompressed files into one big .sqr file but...  you know,
 without any feedback I assume that nobody is interested.  I was even
 successful to create a big EXE consisting of a VM and that archive attached
 to the file and handed over all code to Andreas. >>
