Nitpick back at ya: under AmigaDOS, "*" isn't a wildcard.  In any case,
it sounds like part of the problem with programs accepting wildcards in
general: it takes work on the part of the programmer.  Some of the 
compilers out there have very simple-minded pattern matching functions;
probably where ZOO got it's "*".  Under UNIX, the shell expands the 
wildcards, so that's not really a problem with UNIX zoo (though UNIX
runs into a different problem -- the normal command-line buffer is too
short for many of the multi-level archives I've built.  That's a good
argument for program expansion vs. shell expansion in this case).

It sure sounds like it's creating some temporary files in the current
directory, which is probably a UNIX-ism.  It would work better in the 
general case if, when making temporary files, it put them in "T:", the
proper place for temporary files on the Amiga.
