If the IWMA is stored in a zip file and the program code is in Java then
there is a natural congruence because of jar files. (Thoe who don't know,
and I wish I didn't, jar files are used with the Java programming language
to contain the executable versions and the jar format is nothing more than
a version of zip. Not sure of the exact details I think it has more to do
with named files being present than with encoding/decoding schemes.)

As an aside I'd prefer to have the glyphs stored in a resizable format
such as SVG than in PNG/GIF/JPEG, vector rather than pixel based. (Stored
lines rather than dots.)

As an ex-programmer looking to use IWMA for his signing I personally would
still need to have more than one subset. Stuff I've done recently involves
lexical borrowings (typically from ASL but I've just had to think about
NZSL and AUSLAN to name but two) into BSL.

Long time since I had anything to do with ISO's font people (they speak a
very different language to the rest of us :-) so I'll refrain from
discussing that point ... for the moment. ;-)
